Recently bought this car from #BMW of Santa Rosa. A poorly maintained car from a dealership, go figure. Initially the check engine light came on, Mass AirFlow Meter problems and fuel trim. Considering the MAF meter is part of the Fuel system (air, fuel, spark), cleaning the MAF with #CRC Mass Airflow Cleaner didn’t seem like a bad idea. Cleaned the MAF and reset the light. The light came back on a few days later.
Next I changed the Spark plugs. Considering the mileage they were over due and had not been done yet. The engine still had the same plugs from the factory.
After that was the fuel filter. BMW suggests replacing it at 80,000 miles I believe. The car had 103,000 at the time and it had not been replaced. I reset the light again and it came back on about a week later.
Finally I swapped out the front O2 sensors. The car runs a lot better and the CEL light or Service Engine Soon light has not come back on.

What is fuel trim Bank 2?
Diagnostic trouble code (DTC) P0173 stands for “Fuel Trim Bank 2.” This code indicates that your car’s fuel trims have reached their operational limitations (maximum rich or maximum lean). Fuel trim is the ongoing adaptation that the PCM makes to the fuel mixture to maintain a balanced air-fuel ratio.
How do you reset fuel trim?
This is done by disconnecting the battery, waiting for 10 minutes or so, and/or turning the ignition key to the starter position to discharge the system.
How do I fix code P0170?
To resolve the DTC error code P0170, it is crucial to check all Bank 1 components and sensors likely to malfunction and get damaged. Replacing fuses, connectors, and vacuum pumps might solve the problem in the short term.
What is a fuel trim Bank 1?
Diagnostic Trouble Code (DTC) P0170 stands for “Fuel Trim Malfunction (Bank 1).” Fuel trim is the adjustment made by the PCM to the engine’s air-fuel mixture. The P0170 code indicates that the fuel trims have reached an abnormally low or abnormally high value for a specified amount of time.
How do I fix my fuel trim Bank 2?
- Replacing the mass air flow sensor.
- Replacing the fuel pressure regulator.
- Replacing the intake manifold gaskets.
- Repairing or replacing the engine air filter intake system.
- Replacing a vacuum line connected to the throttle body.
- Repairing a leaking brake booster.
What causes fuel trim issues?
Plugged injectors, fuel filters and weak pumps can cause a lot of fuel trim issues. If the code shows a rich condition, over-fueling could be causing the engine to get more fuel than prescribed. Leaking canister purge valves, lack of maintenance, and contaminated engine oil are all potential issues.
How do you diagnose fuel trim?
The fuel trim value is read by plugging a scan tool into the OBD II diagnostic connector located under the instrument panel (on the drivers side near the steering column). When the key is turned on, the scan tool will initialize and start to communicate with the vehicle’s onboard computer.
How long does it take for long term fuel trim to adjust?
In general, it takes anywhere from five to 20 seconds for LTFT to change, and since it’s stored in memory when the engine is switched off, that same LTFT value is used next time the system goes into closed-loop operation.
What should my fuel trim be?
So what should fuel trim values be? Assuming that the engine is in excellent mechanical condition, and that all sensors implicated in metering both intake air and fuel, short-term fuel trim values should generally be between positive 10%, and negative 10% when the engine is running at a steady speed.
What does engine code P0171 mean?
What Does Code P0171 Mean? P0171 definition: Bank 1 has too much air or not enough fuel. Issue Severity: MODERATE– Extended driving with this code can cause internal engine damage. Repair Urgency: Get this code fixed as soon as possible to avoid damage to spark plugs, pistons, and catalytic converters.
What does fuel trim indicate?
What is Fuel Trim? Fuel trims are what engine control system use to compensate for all problems relating to air-fuel ratios (known as λ or lambda,) and combustion. The Electronic Control Module (ECM) or Powertrain Control Module (PCM) uses a few sensors to determine how much air is flowing into the engine.
What should Ltft be at idle?
The LTFT on a cold engine at idle starts at +1.6. As the engine warms to operating temperature the LTFT creeps up to 21.9 at idle. This seems to go up in line with the intake air temperature. On hotter days the LTFT creeps up further to +25 on a hot engine.
What causes positive fuel trim at idle?
During idle when the throttle plate is closed, the vacuum in the intake manifold is high and very little air flow is entering the engine, so even a small amount of un-metered air will have an effect on fuel trim. This forces the PCM to react to the lean condition with positive valued fuel trim readings.
What should fuel trims be at idle?
Ideally, long-term fuel trims should be at, or close to 0% when the engine is running at a steady speed. However, while changes to the engine speed will (and must) produce changes in the long-term fuel trim value, this value should return to a point close to 0% when the engine speed steadies.
What should fuel trim readings be?
Good LTFT values should be as close to zero as possible, though they can range from 5 to 8 percent depending on the condition of the engine. If the LTFT is getting up around 10 percent or higher, it usually indicates a problem that needs to be diagnosed.
Which side is Bank 2 on?
Bank 2 is the side with cylinder 2. Most commonly Bank 1 is towards the front of the car if it has a transverse engine. The easiest way to discover the right cylinder bank is to check your car’s repair manual.
What causes a negative fuel trim?
But when the engine is in boost mode and positive pressure is provided in the intake, the vacuum leak will allow boost air to escape. This causes the fuel trim numbers to become negative during a boost situation. This happens because the PCM is supplying fuel for the amount of air the MAF sensor measured.
Importance of Reseting Fuel Trim (LTFT).
Post by Brucebo » 08 Jun 2009, 14:46
It is extremely important to reset your Long Term Fuel Trim (LTFT) after any work that could possibly affect the engine fuel and ignition system. This incudes, but is not necessarily limited to:
Oxygen Sensor
MAF Sensor
MAP Sensor
IAT Sensor
Coolant Temp Sensor
Throttle
TPS Sensor
IAC Valve
Any Vacuum Line
Fuel Pump
Fuel Injectors
Fuel Pressure Regulator
Purge Valve
Cannister Shutoff Valve
Spark Plugs
This is done by disconnecting the battery, waiting for 10 minutes or so, and/or turning the ignition key to the starter position to discharge the system. Note, the code “Erase” button on scanners does not reset the LTFT, at least not on my S70. Not reseting the fuel trims provides for a small chance that your adaptive fuel map could fail to converge and/or become unstable.
Bare with me, this article somewhat technical.
The fuel map is a two dimensional table of values, sort of like an Excel spreadsheet, for how much fuel to squirt, based on engine RPM and load value. It consists of the “base fuel map” (BFM) which is hard coded into the ECM, and the adaptive LTFT. In addition there is the Short Term Fuel Trim (STFT). This is a dynamic real time variable fed back to the ECM by the Oxygen Sensor(s).
The BFM is unchanging and is based on the automotive engineer’s, or aftermarket upgrader’s best estimate of what the fuel map should be, given nominal engine design, fuel, and sensor calibration. Added to the BFM is the LTFT, which adjusts for sensor drift, engine wear, fuel, etc. The LTFT is basically a long term running average of the STFT. If the BFM was perfectly adjusted, and unless something is broken it is usually pretty close, the LTFT would be zero everywhere in the table. It SHOULD be fairly small values everywhere in the table. Once the LTFT is fully adapted, the STFT should swing about zero.
The fuel map needs to be a “smooth” or “continuous” function. By this I mean that small changes in engine operating conditions should produce only small or no change in the fuel map value. For example, all else being the same, for a fuel map value at 2000 RPM, you DON”T what the map value at 2001 RPM to be something completely different! This would wreak havoc on your engine.
Here’s where the necessity of reseting the LTFT comes in. If you have a bad sensor, or a loose vacuum line, etc. Your Oxygen sensor will send back large adjustment values of STFT. These will slowly get added to the LTFT and it will adapt. Here’s the rub. Not all the values in the LTFT will adapt at the same rate. A value will only get adapted when you’re driving in that region of the fuel map (combination of RPM and load). Most drivers are creatures of habit and rarely cover their whole fuel map in any reasonable period of time. Your fuel map will start to diverge, become discontinuous and, especially during Wide Open Throttle (WOT) when there is no feedback from the O2S, you will experience surges and hesitations as you swing through the fuel map. Even during non-WOT your O2S feedback takes at lease 1/2 to 1 second to respond so you may still experience surges and hesitations.
Now let’s say you go and fix your mechanical problem but don’t reset your LTFT. These fuel map discontinuities are still there! They MAY adapt back over time, but this could take awhile, and in the mean time you will still experience surges and hesitations. But worse things may happen. The fuel map adapting ability is really only reliable for “SMALL” corrections. In electronics it’s call “small signal analysis”. If the adaptive algorithms are presented with LARGE correction imputes, it is entirely possible that the adaption may diverge and/or become unstable through positive feedback. Let me give a somewhat contrived example. Let’s say at 2000 RPM the LTFT is +18% and at 2050 RPM the LTFT is -18%. The engine hits 2000 and gets some more fuel and revs to 2050. The O2S reads “rich” and sends a negative correction, but since there is some time delay it sends the negative correction to the entry for 2050 and the LTFT goes to -20%. In the meantime as the engine hits 2050 it now gets less fuel and goes back to 2000, the O2S reads “lean” and the process happens in reverse, and so on … . And the owner is pulling his hair out looking for “vacuum leaks”, or replacing “bad” sensors when all they really needed to do was unhook the battery for a few minutes.

P0170 Code – What Does It Mean & How To Fix It
This is one of the most frequent OBD2 trouble codes . Read the full article below to know what it means, how to fix it, and what other codes may show related to it.
When your car’s engine is working at its peak performance, the readings of oxygen sensors indicate that your engine requires more fuel, for which the PCM carries out a positive trim. However, oxygen sensors indicate a negative trim when excess fuel is pumped into your car’s engine. The car’s mainframe computer or the PCM is solely responsible for carrying out this process instantly and efficiently. The car’s PCM detects error code P0170 when an inconsistent fuel consumption rate does not comply with set ranges. The occurrence of error code P0170 directly indicates a problem in the air to fuel ratio and fuel trim controllers in the car’s mainframe computer.
The generic error code P0170 appears when there is a significant problem and mechanical malfunction in your vehicle’s fuel trim in Bank 1. Your car’s Power Control Module (PCM) is responsible for maintaining your vehicle’s entire indoor and outdoor ecosystem. PCM receives direct signals from oxygen sensors highlighting the amount of fuel the engine requires. According to your engine’s fuel consumption rate, PCM adjusts the amount of fuel by undergoing a positive and negative fuel trim.
Causes
Many potential causes can be the reason for the occurrence of DTC error code P0170. Mechanical and electrical failures in your car’s engine can potentially cause a malfunction. Moreover, clogging in the fuel filter can create a physical barrier between the fuel pump and the generator. Furthermore, variable fuel pump pressure and frail fuel pump can also cause the error code P0170. To find the definite problem, one should thoroughly inspect every connection linking bank 1 sensors and the engine. Listed below are the few possible causes that might trigger the DTC error code P0170.
Leak or malfunction in turbo air change hoses
Malfunctioned injector
Saturated or contaminated engine oil
Clogging in air filter
Blockage in the air intake system
Possible malfunction in the catalytic converter, muffler and exhaust pipe
Damaged coolant and airflow sensors
Frayed wiring and connections
Accumulated dust and carbon between connectors and fuses
PCM software issue
Symptoms
A severe malfunction of your engine’s fuel trim would impact your engine’s overall performance and fuel consumption. You might notice a slight decrease in your car’s mileage and fuel consumption ability. However, when the PCM detects the DTC error code P0170, there must be a definitive problem in your engine’s fuel trimmers. Mentioned below are possible symptoms one could experience and notice.
Illuminated check light on the dashboard
A significant drop in your car’s fuel mileage
Upon acceleration, the engine loses its efficiency and starts vibrating
Misfiring and suffocation in engine
Diagnosis
As the PCM detects the DTC error code P0170, it is imperative to do a detailed inspection of your car’s engine room and Bank 1 sensors. To find the root cause of the error code P0170, one should inspect all connections, sensors and main engine units. If your car’s engine is misfiring and having issues in maintaining the air to fuel ratio, your car’s PCM would directly show the error code P0170. One can start their self-diagnosis by following the user manual or the user’s guide.
The self-diagnosis of the error code P0170 may include the following steps:
Restart your vehicle and check whether the error code is reoccurring
Reset your PCM, and check for software updates
Check connectors, wirings, plugs and fuses
Inspect oxygen, airflow and coolant temperature sensors
Clean accumulated dust, carbon and soot in the connectors
Ensure the entire circuit is complete and functional
It is recommended to consult a professionally trained mechanic or an automobile technician who uses an OBD-II scanner to find out the root cause. The mechanic would freeze the PCM using the OBD-II scanner and deduce the main problem causing the DTC error code P0170. Moreover, the mechanic would start his preliminary analysis by visually inspecting the connectors, wirings, circuits, and integrated sensors in Bank 1.The automobile technician would start his analysis and follow the below-mentioned steps to evaluate the components causing the DTC error code P0170.
The automobile technician would use an OBD-II scanner to scan the PCM. After the initial scan, PCM would indicate the potential malfunctions causing the DTC error code P0170.
The mechanic would also observe and check Mass Air Flow Sensors that might be damaged and need replacement. Moreover, after disconnecting the sensors, he would search for possible leaks in the regulator, causing variable fuel pressure.
Next, the mechanic would closely inspect all vacuum hoses and ensure no cracks or openings are causing air level fluctuations.
The mechanic would also check all connections, wirings, and fuses in the primary circuit. Moreover, he would review oil levels and terminal circuits to ensure they comply with the brand’s specifications.
Common mistakes
While diagnosing the cause of DTC error code P0170, one shouldn’t replace airflow or oxygen sensors without consultation. At times, users search for online solutions and immediately take action by replacing the sensors in Bank 1. However, you must always consult a professional mechanic who would conduct a detailed inspection of your car’s engine and search for specific problems causing the error code P0170. Before any replacement, one should always clean the contaminated dust, carbon and impurities on sensors and other connected components.
How serious is this?
When your car’s PCM detects the error code P0170, you must resolve it on a priority basis. The reoccurring error code P0170 can impact your engine’s health and affect its overall functioning and efficiency. Moreover, this would impact your car’s mileage and cause problems during ignition and acceleration. If the error code P0170 isn’t repaired, it would cause severe problems in the short term and affect your vehicle’s drivability.
What repairs can fix the code?
To resolve the DTC error code P0170, it is crucial to check all Bank 1 components and sensors likely to malfunction and get damaged. Replacing fuses, connectors, and vacuum pumps might solve the problem in the short term. However, it is advisable to consult a qualified motor technician.

Conclusion
Every driver aspires to enjoy a hassle-free drive, which is only possible if you regularly maintain your vehicle and check for significant repairs. To avoid DTC error code P0170, it is imperative to check your engine’s oxygen sensors which are responsible for balancing the fuel trim. To improve your vehicle’s mileage and fuel consumption, it is vital to check and clean oxygen and airflow sensors regularly.
Fuel Trim Bank Codes
Fuel Trim Bank Codes 2004 E53 X5 3.0, 117K miles
Hello, all. I recently had my Service Engine Soon (SES) light come on and instead of going to Autozone for a read, I recently bought a cheap OBDII reader (Creator C310 BMW Multisystem Scan Tool) on Amazon to see what codes it was throwing. They are:
E4 Fuel Trim Bank 2, Permissible Range Exceeded
E3 Fuel Trim Bank 1, Permissible Range Exceeded
I’m relatively mechanically inclined and would like to try and resolve this myself without going to a shop. I bought this ’04 X5 with 106K on it and it now has 117K miles on it and has run well to this point (besides an oil pan gasket I had to have replaced). Upon start, it runs a little rough at idle but smooths out when I’m driving. I’ve cleared the codes and within 1 drive to work the light comes back on and the codes are the same.
I did some Google searches and didn’t really find a smoking gun on what these codes are indicating is specifically wrong. I have cleaned the MAF with cleaner but that didn’t do anything. I’ve read where it can be O2 sensors, the DISA, vacuum leaks, etc., but what I was hoping to find is a methodical approach to resolving the issues instead of throwing parts at it in an attempt to see what works. My son has a 2002 E53 so I thought about swapping the MAFs to see if that makes any difference.
If anyone has any suggestions on a systematic approach to take in trying to resolve this issue it would be greatly appreciated! Thx 2004 E53 X5 3.0, 117K milesHello, all.

Lean codes are driving me insane.
I bought an e46 325xi two months ago with 155k miles on it. Here’s my total replacement list so far: Water pump, water pump pulley, serpentine belt, A/C belt, upper radiator hose (2 of them), Intake cam position sensor, fuel pump (direct result of the lean codes, thought pump went bad), front passenger control arm… And a few more that I’m blanking on. Doing all the labor myself and buying parts from retailers like Advance Auto, Auto Zone and O’Reilly, my bill so far has rang up to about $1800 after purchase, and I currently have two window regulators out as well as dry-rotted speakers. My current warning lights are an airbag light (my code reader says passenger seatbelt tensioner) and my Service Engine Soon light is on, stating that the engine is running lean. I’m tired of spending money, hopefully someone can help me. Here are all the codes I received:
E3 Fuel trim bank 1, permissible range exceeded
E4 Fuel trim bank 2, permissible range exceeded
CA Fuel trim bank 1 ctrl limit
CB Fuel trim bank 2 ctrl limit
Misfires in multiple cylinders, usually 5, 6, and 2 in that order, but 3 and 4 get thrown into the mix every now and then.
If the car starts cold, it will idle what I would call mildly rough. It has no trouble staying running, but it has more rumble than when warm. When the car is warm, if I sit idle for too long I begin to get really bad misfires and it feels like I’m sitting in a large diesel truck. The RPMs fall to just under 500, ramp to 1000, and repeat until the rpms dip just a little too low and the car finally dies. When the car runs, it runs solid. When it pulls this crap, usually all I have to do is restart the car and it’s fine. If anyone has any insight as to how I can fix this problem or why my car is spitting a seatbelt tensioner code, please help!!! Thanks.
E46 B3s Fuel Trim Fault Codes
Post by Henry » Mon Jul 20, 2020 10:45 pm
Mine had a dead pump when I got it and I fitted Pierburg. Been almost a year now without issue but that’s nothing in the expected life of a pump. Unfortunately I haven’t got a pressure tester or I’d have seen what mine reads. As for ECUTesting the module was under a lifetime warranty from them from 2018. They sent it back saying no faults but they had tidied it up a bit. Fitted and lights still on but with a different fault showing. They suggested sending the pump and module back, after a few days they rang to tell me the module was beyond repair but pump seems ok.?? Gave me two options. Take the £254 back that they charged to fix and issue warranty back in 2018. Or they will try and source a replacement at £404 and will have their warranty. As I have long ago wrote off the original £254 I have gone for the second option and in my head I’m only £150 out of pocket. They tell me it could take 2 weeks to source and inspect. Tad suspicious as to how it was sent back as ok and now it’s beyond repair.

Update – just had a poke around, soaked the whole area in carb cleaner without any consistent results – unplugged the MAF and it ran much better. Not sure if this points to anything in particular as I am assuming it has a default setting as it doesn’t know how much air is going in. Might dismantle and inspect the DISA tomorrow.
Fit a genuine BMW MAF, as others have said, aftermarket ones are stty at best.Get the DISA rebuild kit from X8R on eBay, c£60. Takes 30mins to remove, dismantle, rebuild and refitWorth doing as it’ll never need doing again.Also make sure that your air intake boot from MAF to throttle body isn’t split anywhere; these are known culprits, so worth checking and replacing if necessary (the Febi parts via BMWmotormec on eBay are more than sufficient)
