Got a code P0175 dont no where to start?

That code indicates you are running a rich fuel mixture on bank 2. Many things can cause this problem.

Follow this procedure:

1) Start the vehicle to get it warmed up (let it run for about 15 to 20 minutes) and connect your Scan Tool to the OBD II Diagnostic connector.

2) po175 indicates a rich mixture (bank 2 / cylinders 2, 4, 6, 8)

3) Once connected, go to Live Data mode and scroll down to the PID that's labeled: LT FTRM1 and LT FTRM2 Select LT FTRM2 If a rich condition is present, the reading will be around - 20.
If that is the case, there is actually a problem causing the PCM to run it that rich. The PCM is not the problem.
