When to use the error code p0170 on fuel trim?
If the signal from the O2 sensor means the engine needs less fuel, the PCM acts accordingly through a negative trim. If the O2 sensor says it needs more fuel, then the PCM will carry out a positive trim. Error Code P0170 is set when the PCM has detected an anomaly on fuel (fuel trim) that is outside the range of the vehicle’s specifications.
What does the PCM error code p0170 mean?
Error Code P0170 is set when the PCM has detected an anomaly on fuel (fuel trim) that is outside the range of the vehicle’s specifications. This can be a negative or positive trim. This code means there’s a malfunction in the computer’s control of air to fuel ratio.

What does Bank 1 fuel trim malfunction mean?
Error Code P0170: Fuel Trim Malfunction (Bank 1) Error Code P0170 is described as Fuel Trim Malfunction Bank 1. This means the PCM (powertrain control module, also known as ECM or engine control module) has detected a fuel trim outside the specified range set by the vehicle’s manufacturer.
If the signal from the O2 sensor means the engine needs less fuel, the PCM acts accordingly through a negative trim. If the O2 sensor says it needs more fuel, then the PCM will carry out a positive trim. Error Code P0170 is set when the PCM has detected an anomaly on fuel (fuel trim) that is outside the range of the vehicle’s specifications.
What does a p0170 mean on a PCM?
When the fuel trims reach their rich correction limit, the PCM (Powertrain Control Module) sets a P0170, indicating a problem or malfunction in the fuel trims. It may also have a P0173 referring to the same malfunction but on bank two. Symptoms of a P0170 DTC may include:
