Why is my check engine light on with no code?
If you can’t pull any codes, it’s most likely due to having the wrong scanner or one that is incompatible with your vehicle. There could also be an electrical short or blown fuse causing the light to come on for no reason. Also, consider the chance that user error or a contaminated port is to blame.
How do you reset the check engine light on a Cummins?
Close the doors and insert the key into the ignition. Cycle the key five times from “off” to “run” without actually cranking the engine. On the fifth cycle, leave in run.
How do you reset check engine light without tool?
The best way to reset the check engine light without a scan tool is by removing the battery terminal for 30-60 seconds. This will reset the engine control unit in many car models.
How do you reset the check engine light on a 2018 Ram 2500?
Will the check engine light reset itself? The check engine light on your 2018 Ram 2500 will usually shut itself off if the issue or code that caused it to turn on is serviced. For example, if the cause of your check engine light coming on was a loose gas cap, if it’s tightened, the light will turn itself off.
Why is my engine light on but nothing seems wrong?
If nothing seems to be acting strange, then it is probably safe to drive it until you can get it into a mechanic. Sometimes the light may come on after fueling if the gas cap is a little loose. Or it could mean your catalytic converter needs to be inspected.

What does a solid check engine light mean?
A solid Check Engine Light can mean something like a loose gas cap, or it can indicate a more in-depth problem like a fuel, timing, or transmission issue. Get your car diagnosed, although the urgency isn’t the same as if the light was flashing at you.
How To Get Rid Of The Check Engine Light ( 5 Easy Methods )
The Check Engine Light has long confused motorists with its vague warning. When it comes on, it’s unclear whether you should keep driving or have your car towed. Here’s everything you wanted to know about the Check Engine Light:
What the Check Engine Light does
The Check Engine Light has one purpose: to let you know when you have a problem. That’s all. It doesn’t tell you what the problem is; A technician will need to perform a diagnostic scan to check the affected system. It just indicates that something is not working properly.
The Check Engine Light is also known as the Malfunction Indicator. It is shaped like an engine and yellow in color. Most vehicle systems perform self-tests under certain operating conditions and the results are reported to their respective control modules. If a self-test fails under certain parameters, your car’s Check Engine Light will illuminate. It could be an engine, transmission, or exhaust system that failed the test.
What does the check engine light mean?
There are two different ways the Check Engine Light can illuminate: solid or flashing. They mean two different things.
If the engine light comes on and flashes, it indicates an imminent problem. You must find a safe place to stop and turn off your vehicle. You might want to consider having it towed to the shop. A technician needs to diagnose the problem as soon as possible to avoid damage to your car. A blinking Check Engine Light is serious business.
Having the engine light on constantly can still be a cause for concern, but it doesn’t have to instill fear in your heart right away. A solid Check Engine Light can mean something like a loose gas cap, or it can indicate a deeper problem like a fuel, timing, or transmission issue. Have your car diagnosed, although the urgency isn’t the same as having the light flash towards you.
Common reasons why the check engine light comes on
The reason for an engine light could be a risk of catastrophic failure, or something that needs immediate attention, or it could be nothing at all. Because the vehicle’s systems perform self-tests, it is possible for a test to fail and the check engine light to illuminate and the next test to pass. The Check Engine Light may not turn off once it’s over, and it may not even turn off until a technician clears the code, although no repair is required at all. Common reasons for the Check Engine Light are:
The gas cap was left loose when refueling
Emission-relevant sensors such. B. Oxygen sensors have failed
Engine timing problems, most common with variable valve timing
Transmission Error Codes
Engine misfire codes
catalyst problems
There are literally dozens if not hundreds of other reasons for the Check Engine Light to come on. If it lights up, have it checked appropriately. Do not take unnecessary risks if you feel that the vehicle is not operating safely. Have your vehicle towed to the workshop if you do not feel safe driving. If the Check Engine Light is flashing, it is in your best interest to stop driving until the light is diagnosed and repaired.
Will check engine light reset itself?
Will Check engine light reset itself? Your car’s check engine light will reset itself after you repair the problem in most car models. But it may take some time. A car usually needs 10-20 successful cycles before it will reset the check engine light by itself.
How To Get Rid Of The Check Engine Light ( 5 Easy Methods )
Your car’s dashboard has many warning lights that let you know when there is a problem with your car.
They have turn signals, headlights, a fuel gauge, a check engine light and more.
There are those scary moments when the check engine light stays on and the question is will the check engine light reset itself after I fix the problem?
Let’s find out!
Does the check engine light reset itself?
Your car’s check engine light will reset itself on most car models after you fix the problem. But it may take some time. A car typically takes 10-20 successful cycles before it resets the check engine light on its own.
A cycle is when you start your car from cold and drive it until it’s warm, and then until you’re done driving.
When you are sure that you have fixed the problem causing the check engine light, the check engine light will reset after 10-20 successful cycles and as you can imagine, 10-20 successful cycles can take a long time. Therefore, it is much easier to reset the check engine light using an OBD2 scanner.
What if it doesn’t reset itself?
Some car models do not reset the check engine light themselves; You need to reset it with a scanner.
If your check engine light doesn’t reset itself, you’ll need to use an OBD2 scanner to do it. If you want to reset the check engine light using an OBD2 scanner, you can follow this guide: How to reset the check engine light.
For the check engine light to reset itself, you need to fix the problem and not expect it to just go away without doing anything about it.
Why you shouldn’t ignore the check engine light
If you’ve seen this light on the dashboard, please don’t expect it to go away and ignore it as it could lead to more serious problems.
Most modern cars have onboard diagnostics. This system consists of a car computer that monitors various sensors in several car components. If your car has a problem, the sensors will detect that problem and send it to the on-board computer to display a warning light on the dashboard.
Ignoring the check engine light can cause several other problems with your car.
What is the most common reason for check engine light?
Oxygen Sensor
A faulty oxygen sensor will return a check engine warning every time. In fact, it’s one of the most common reasons why a check engine light comes on while you’re driving your automobile.
How To Get Rid Of The Check Engine Light ( 5 Easy Methods )
1. Catalyst
Hopefully your check engine warning doesn’t come on because your catalytic converter is failing. The only reason we are saying this is that replacing the catalytic converter can be expensive and your vehicle cannot run without it. The catalytic converter is part of your vehicle’s exhaust system and if you notice a rotten egg smell along with the engine warning message, this is likely the problem.
2. Fuel cap
Hopefully your Check Engine warning came up because you didn’t tighten your gas cap the last time you filled up a car, SUV, or truck. A loose fuel cap gives an engine check warning because the cap should create a vacuum seal once you tighten it. If your cap is loose because you didn’t tighten it, cracked, or if the seal is broken, your engine check warning will appear.
3. Mass Air Flow Sensor
The mass air flow sensor in your vehicle’s engine measures the air entering the engine to ensure the correct amount is mixing with the fuel. If you are not getting the correct air/fuel mixture, your engine may stall or refuse to start. When the mass air flow sensor fails, your check engine light will come on because the on-board computer has received a signal that there is a problem with the air/fuel mixture in your engine.
4. Oxygen sensor
The same applies to the oxygen sensor. This crucial part measures how much unburned oxygen is in your car exhaust, and if there is too little or too much, other engine parts can be damaged. A faulty oxygen sensor returns an engine check warning every time. In fact, this is one of the most common reasons why a check engine light comes on while you are driving your car.
5. Spark plugs
Finally, worn spark plugs or spark plug wires will result in an engine check warning. Almost anything wrong with your vehicle’s ignition system will likely cause your check engine light to come on. If your plugs haven’t been changed and your vehicle has driven over 100,000 miles, it’s time for new plugs and possibly new wiring. Stalls are another indicator of spark plug problems.

Sometimes your check engine light won’t turn off even after you fix the problem with your vehicle. In this case you have to reset the light manually. One way is to turn the ignition on and off three times in a row. Then drive your vehicle around and see if the light goes out. If that doesn’t work, turn off your car, open the hood and disconnect the positive and negative cables from the battery. Press the horn for 30 seconds to drain the remaining power, then wait 15 minutes before reconnecting the battery cables. Disconnecting the battery in this way can reset your car’s electrical system and clear the trouble code that is causing the check engine light to stay on. If all else fails, buy an OBD code scanner and plug it into your vehicle’s OBD port, which should be located under the steering column. Turn on the scanner and wait for it to scan your vehicle for trouble codes. When it’s done, you can clear the trouble codes that appear on the scanner, which will turn off your check engine light. To learn how to reset a check engine light with a code scanner, read on!
How do you reset the check engine light on a 6.7 Cummins?
You can do this by constantly blowing the car’s horn until it dies or turning on the headlights, then waiting several minutes. This will ensure all electrical current has been drained from the car’s capacitor. At this point, it should be safe to reconnect the battery and the check engine light should not longer be lit.
How To Get Rid Of The Check Engine Light ( 5 Easy Methods )
On some cars, particularly those made before the mid 1990’s, you can reset the check engine light by disconnecting the battery. However, newer vehicles have a feature that simply turns the light back on after reconnecting the battery if the car isn’t properly drained. You can do this by constantly honking the car’s horn until it goes off, or turning on the headlights and then waiting a few minutes. This will ensure that all electrical current has been drained from the car’s capacitor. At this point it should be safe to reconnect the battery and the check engine light should no longer illuminate. Disconnecting the battery will erase all data from the vehicle’s computer, which could make it harder to diagnose problems with the car in the future. It will also reset the electronic systems in the car; For example, if the car has an anti-theft radio system, it will likely go into safe mode and require a code to unlock it. All radio station presets must also be reprogrammed. If you’re trying to turn off the light in hopes of passing an emissions test, this method rarely works. Even if all emissions data is erased from the computer when the battery is disconnected, the car’s systems must go through a series of tests called a “drive cycle” before it can pass the test. Sometimes more than one drive cycle is required before the car is complete. The chances of the car completing its internal tests and not turning the lights back on before the emissions test is on is very slim.

Check Engine Light Is On But No Codes – Causes & What to Do?
If your check engine light is on but you haven’t stored any trouble codes, there are a few possible reasons why this might be the case. Read on to find out!
When the Check Engine Light comes on on your dash, it is an indication that there is a problem. In most cases you would pull out your code scanner and see what is causing the error. So what do you do when you can’t find any diagnostic trouble codes to show you what the problem is? While this is a rare case, there are reasons the Check Engine Light may be on but no codes are displayed.
If you are unable to pull codes, it is most likely because you have the wrong scanner or one that is not compatible with your vehicle. There could also be an electrical short or a blown fuse that is causing the light to come on for no reason. Also consider the possibility that user error or a contaminated port is to blame.
In this guide, we’ll take a closer look at what can cause this rare event. We also examine what you can do about it so you can read the codes or diagnose the fault.
What is the Check Engine Light?
The Check Engine Light is also known as the Malfunction Indicator. This light illuminates on the dashboard to alert you to a problem with your vehicle’s engine computer.
Check Engine Lights can appear in different colors depending on the manufacturer. Usually this light is yellow, orange or amber. If the light is solid, there is an error code that needs to be read. However, when the light is blinking, it is an indication that something important is happening that needs immediate attention.
Reasons why the check engine light is on but not codes
1. Wrong code reader
No two code scanners are the same. You can find many inexpensive diagnostic scanners on the market that will read the most basic of codes, but these won’t give you everything you need for the exhaust system or transmission.
If you go to a local auto parts store for a free code scan, they won’t pull out an expensive diagnostic tool. Instead, you’ll get a basic scan that may not include the specified codes.
Here are some good scanner alternatives: Best OBD2 Scanners
2. Electrical short circuit
An electrical short is unlikely to be causing your problems, but not impossible. If a short occurs anywhere in the system, the power supply could jump to the light and force it on.
You can check this by turning the key to the on position without starting the engine. The light should go out after a few seconds. If not, a short could be the problem.
3. User Error
While you might think you’ve got automotive diagnostics under your belt, there’s always a chance you’ve missed something. Although the code reader is an easy-to-use tool, you can’t overlook the possibility that you’ve done something wrong.
Take a moment to re-read your scan tool’s manual. Follow the instructions no matter how simple they may be. It’s possible you’ve missed something fundamental.
RELATED: Check Engine Light – Meaning and Causes
4. Blown fuse
If the code scanner is plugged into its port but nothing is being read, you may be thinking about destroying the OBD2 device. Don’t throw it away entirely just yet, because a blown fuse could be to blame.
The engine control module (ECM), electronic control unit (ECU) and powertrain control module (PCM) are all fused, just like the other electrical devices in your vehicle. If the fuse blows, the juice cannot get to the required component. The light may come on when there is no actual fault. Read the owner’s manual to find out which fuses to check.
5. Contaminated port
When you are ready to use the OBD2 scanner, plug it into the appropriate port under the dashboard. If the scanner isn’t working or getting codes, there could be a problem with the connection itself.
Examine the connector to determine if dust or dirt has contaminated the connector. Luckily, this should be an easy fix that only takes a few seconds.
What is an OBDII code scanner?
OBD2 stands for Onboard Diagnostics II. This advanced diagnostic system has been included in every vehicle since 1996. The technology allows you to check the engine and other vital systems to see what problems are prevalent.
OBD systems remain standard on all new car makes and models. This system uses a universal connector, allowing the device to read a variety of vehicles.
If you want to monitor the condition of your vehicle, an OBD2 scanner to read engine codes is essential. However, different code readers are designed to diagnose different systems, so you need to be careful about which one you buy.
RELATED: How to Reset a Check Engine Light
How to fix check engine light without codes
The first place to start is to look at the code scanner. Are you using the right scanner and is it capable of reading a variety of codes? If you haven’t already invested in a quality scanner, now might be the time. Of course, the scanner can also be defective. Try it on another vehicle to see if it works properly. If not, it’s time to replace it.
You should also check the port you are plugging it into. If the connection is clogged with dirt, use some compressed air to clean it out.
Your next step would be to check for a blown fuse. The location of the fuses can be found in the operating instructions. Locate the fuse that operates the ECU, ECM, or PCM and see if it is blown. In this case replacing the fuse should only cost a few dollars and the Check Engine Light should go out.
Anything beyond these simple fixes may require a professional. If you are unsure how to find an electrical short, you should take it to the shop for further inspection.
How to Clear Cummins Fault Codes

How to Clear Cummins Trouble Codes
It’s almost impossible to work on or repair a Cummins engine these days without knowing the trouble codes. Once the Cummins trouble codes have been retrieved, the next step is to find out what they mean and how to clear them.
What are Cummins Trouble Codes?
Trouble codes indicate that the engine has a problem. Each circuit and sensor in a modern diesel engine gives off a specific reading and a specific voltage signal.
The Electronic Control Module (ECM) in the engine constantly monitors all readings while the engine is running. If the values fall above or below the expected value, the ECM will log an error code. There are three error code statuses:
Inactive : If it occurs at a time outside of diagnostics, it is inactive.
: If it occurs at a time outside of diagnostics, it is inactive. Active: If the error occurs during diagnostics, it is an active error.
: If the error occurs during diagnostics, it is an active error. Pending: A pending code is a code that has not yet been deleted.
Pending codes can also be intermittent errors or errors that need to be “seen” for at least two warm-up cycles to set them active. For example, a code may be active after the problem has been fixed. It sometimes takes multiple drive cycles to clear the code from active status.
There are dozens if not hundreds of trouble codes and they are different for each engine. Therefore, it is important to look for information specific to specific engines when looking for trouble codes.
For example, the list of pre-2002 ISX trouble codes without EGR is a different list than the 2007-2010 ISX trouble codes with DPF. For the former, error code 111 stands for Electronic Control Module. For the latter, 111 has a more specific error: ECM Critical Internal Failure.
The ISX fault codes for the 2007-2010 engine are more detailed than the earlier engine. There are many new ones that don’t exist for the previous engine either. The newer the engine, the more detailed the trouble codes are in most cases.
How to Clear Cummins Trouble Codes
Once all the necessary engine repairs have been performed, the next thing you need to know is how to clear trouble codes. This usually requires software and a diagnostic tool. Connect to the ECM with a code reader and locate the “Trouble Codes” tab.
The displayed codes can usually be clicked individually. Another option is to select “Clear All Errors” and then follow the on-screen instructions. At the end of the procedure, the ignition key should be turned off. Press the appropriate button on the diagnostic device and turn the key back on.
Depending on the powertrain control module (PCM) software or “flash”, the above procedure may not work. If this is the case, an onboard diagnostic scanner (OBD-II) can be used to clear the trouble codes.
Follow these steps to clear Cummins trouble codes with a scanner:
Close the doors and put the key in the ignition
Cycle the key from “off” to “run” five times without actually starting the engine
Leave in the fifth cycle
This will clear any pending or currently active codes. It’s important to remember that the “Run” position is two button clicks. The “Accessories” location is just a button click.
Problems with the Cummins engine
Although Cummins engines are generally reliable, they have to watch out for some common malfunctions. Some of them also depend on the engine model.
Lift Pump – This is part of a fairly complex fuel injection assembly. The main problem with this common failure is that there are no obvious signs that it is about to fail. The rest of the injection system compensates for the weakening suction pump, which puts a strain on the entire system.
Steel Dowel Pins Vibration from the engine and temperature changes can cause these pins to loosen which, if they do, can result in significant damage. This problem is referred to as the “killer dowel pin” by diesel enthusiasts. It is mainly a problem on the 5.9 liter 12 and 24 valve engines produced between 1989 and 2002.
The four main places where the pen can fall out and get stuck are:
The timing case and cam gear, but the case will not be damaged
In the oil pan, but does not damage the housing
Timing gear and cam gear damaging the housing
Cam and injection pump gears that can completely kill the engine
Luckily, diesel parts dealers like ProSource Diesel sell KDP (Killer Dowel Pin) kits to fix and prevent this problem.
Misfires – This is one of the most common problems with diesel engines and usually has something to do with the fuel injectors. Another common reason for misfires is an electrical problem. Leaking or stuck fuel injectors will result in fuel leaching into the engine oil, which is usually an easy way to spot the problem.
Cracked Engine Block – This problem is less common than the other three problems, but it can happen. It is most common on engines made between 1999 and 2002 with a 53 stamp on the block. The problem is due to thin walls of water, which can rupture and allow coolant to enter the engine.
If the problem is not caught early enough, a new lock may be required. Towing and cold running are to be avoided on engines stamped 53.
These are some of the most common Cummins engine problems, but many other problems can also arise. The best way to keep a diesel engine in good condition is to follow recommended maintenance schedules to stay current on preventive repairs and replacements.
Servicing considerations for the Cummins 6.7L
When it comes to following a maintenance schedule, it is important to remember that some items may need to be addressed sooner depending on whether the diesel truck will be used in difficult driving conditions.
Any combination or individual item in the following list indicates severe driving conditions:
Excessive idle
Frequent short trips that prevent the engine from reaching full operating temperature
Driving in a dusty environment
Driving off-road or in conditions that require four-wheel drive
Frequent heavy towing or towing
Most service intervals are also the maximum recommended time or mileage before service should be performed. For example, if every 30,000 miles is the recommended interval for a particular service, that is the maximum amount and the service can and arguably should be performed sooner.
The following is a basic list of maintenance considerations for the 6.7 liter Ram truck diesel:
15,000 miles or 12 months Replace engine and chassis mounted fuel filters
30,000 miles or 24 months Replace engine air filter (check periodically at oil change and replace as necessary)
60,000 miles or 48 months under normal driving conditions Replace transfer case oil (30,000 miles or 24 months under severe driving conditions)
67,500 to 75,000 miles Replace crankcase ventilation filter or as shown on display (2007.5 2018 engines should be done on 67,500 and 2019+ engines at 75,000 max)
Replace the V-ribbed belt every 100,000 miles (check when changing the oil and replace if necessary)
Oil changes on 2007.5 – 2019 Ram Truck engines should be performed at a maximum of 7,500 miles, six months, or 500 hours, whichever comes first. In all cases, the oil change indicator replaces the intervals.
Cummins 5.9L Service Considerations
The service intervals between the 12-valve and 24-valve versions of the second generation Dodge truck engine are very similar. They also use many of the same Cummins parts. How often a Dodge diesel truck is serviced depends on how it is operated.
As mentioned, if it fits one of the heavy usage considerations, it should be serviced more frequently. The following points should be carried out whenever the industrial truck is serviced:
Check steering and suspension systems and parts for wear
Check exhaust system
Check all liquid and oil-carrying components for leaks
Check the truck’s parking lot for signs of leaks
Check brake hoses
Rotate tire and check for damage
Check fluid levels
Check engine air filter
Drain water from fuel filter (should be done monthly)
Oil changes for the 12 valve should be done every 6,000 miles or six months under normal operating conditions. In severe operating conditions, this should be done every 3,000 miles or every three months.
The 24-valve engine can run up to 7,500 miles or six months before an oil change under normal operating conditions. In severe conditions, this should be done every 3,750 miles or every three months.
The fuel filter interval for the 24 valve is the same as the 6.7 liter engine, but for 12 valve engines it should be replaced every 12,000 miles or 12 months, whichever comes first. These intervals remain unchanged even under difficult operating conditions.

How To Get Rid Of The Check Engine Light ( 5 Easy Methods )
Having a check engine light on your dashboard can definitely be annoying. Here’s how to reset it if it doesn’t go away on its own
Our cars are designed very sophisticated. They have many electronic systems, and one part is the car’s on-board diagnostics (OBD) system.
Some of the possible malfunctions in your car can be detected either through various inappropriate noises or through various physical signs. But some faults that are not easy to detect but occur in your vehicle are indicated by the check engine light in your car.
In this article we will go through how to reset the check engine light.
How to reset the check engine light
The easiest way to reset the check engine light is to use an OBD2 scanner. But if you don’t have one available, you can often do without one.
Here are a few different ways you can reset your Check Engine Light: Total time: 5 minutes 1. Use an OBD2 scanner If you have an OBD2 scanner available you can reset your Check Engine Light in seconds. To get one, you can read our other article on the best OBD2 scanners you can buy.
If your check engine light is on, connect the scanner to the OBD port located under the steering section of most car models. Then switch your car’s ignition to the ON position. After the connection between the computer and the car is established, press the “Read” button on the scanner to search for all stored trouble codes.
After the scan is complete, make a note of any trouble codes diagnosed by the scanner and decode those issues using the specific make and model’s instruction manual. Once the code is decoded, the problem will be identified. Solve this problem; If this part needs to be changed then change it or if it needs to be calibrated then do the calibration.
When finished, clear the error from the scanner by pressing the Clear/Clear button. Once the problem is resolved it is recommended to turn the ignition off and then back on again, check that the check engine light does not come back on and check again from the scanner to see if the same error comes up again or not. 2. Battery Disconnect Technique The best method to reset the check engine light without a scan tool is to remove the battery clamp for 30-60 seconds. This will reset the engine control unit on many car models.
First remove the negative terminal of the car battery. Then try to discharge the current present in the car’s capacitor by pressing the horn or turning on the lights for about 20-30 seconds. Once the power is off, leave your car for 10-15 minutes. After this brief period, reconnect the battery terminals, making sure they are tight to avoid possible sparking, then turn on your car. If your car shows the same check engine light after restarting, it means there is some serious problem in your car or your car is storing the codes anyway. In such a case, it is highly recommended to check the codes with a scanner instead, as some car models do not reset the codes by disconnecting the power. 3. Turning the ignition on and off Turning the ignition on and off is also a method of hard reset without disconnecting the batteries. Put the keys in your ignition and turn your ignition on and off after one second at each step.
Once this is done, check if the check engine light is still on or not. If the check engine light is off you’re good to go, but if it’s still on, brace yourself by reading the codes with a scanner instead. 4. Let it go off on its own Another way to reset the check engine light is to wait and let it go off on its own. It’s a simple method; You just have to wait about three days and continue driving your car. Car computers work in a continuous cycle, updating their current state.
Keep in mind that before trying this technique, you need to make sure that the problem is resolved.
For example, if the ECU detects an issue in the oxygen sensor that could be due to a minor malfunction, it may fix itself automatically as the ECU will update the status of the sensor once the malfunction is fixed, triggering the check engine light. However, if your check engine light is still on after three days, either try the above methods yourself or take your car to a mechanic. Read more about it here: Will the check engine light reset itself? 5. Remove and reinsert fuse One of the ways to turn off the check engine light is to remove and reinsert the engine control unit fuse. Although this doesn’t solve the problem on newer cars, it can solve the problem on slightly older cars and it’s easy to try. Check your repair manual to locate the fuse going to the engine control unit.
When the check engine light comes back
Once your check light is gone using any of the five methods above, you are good to go. However, if your warning light comes on again after a few days, it means that there is a problem in your car that needs to be fixed.
Now is the time to really get your car diagnosed with a scanner. Either by buying one yourself or going to a garage that can read the codes in your car.
