Ther are a few things that can cause a lean condition. A weak fuel pump or pressure regulator, clogged air filter or fuel filter. defective altitude sensors, vacuum leaks, defective 02 sensor. Only way to know for sure is thru diagnosing. The longer you wait to have it done the more damage you will do to the catalytic converter.

What does code po171 mean


System too lean (bank 1)
Not enough gas in mixture

May 25, 2016 | 2002 Dodge Dakota Club Cab

1 Answer

P0444


code po444 is referencing a purge control problem. this could be a bad connection or a problem with the purge solenoid for the evaporative system(EVAP). this is controlled by the PCM to allow fuel vapours to be drawn into the engine and burnt from the gas tank under certain conditions. the p0174 is a lean running condition on bank 2 and p0171 is a lean running condition on bank 1. the lean running conditions could be O2 sensors, lean condition caused by bad fuel pressure, dirty injectors, bad MAF sensor, vacuum leak.

What is the meaninig of code 0171 0714


Code 171 is the fuel mixture is too lean on bank one which is the side with cylinder one.
Code 714 is a problem with the trans fluid temp sensor circuit.
The O2 sensors for bank one and the temp sensor would need to be tested.
