Do you have the specific code numbers that are stored?



Customer: replied 6 years ago.

I didnt write them down but I think they were 0172 & 0174


When the light comes on again I will write the codes down

Expert:  Virtual Wrench replied 6 years ago.



Those are both Or sensor related, but they are actually oposing each other as one is lean and one is rich. If the codes have not been erased they will still be in the computer, otherwise just wait until the light comes back on and get them again and post them here and we can look them up to be more specific because it could be both sensors and or converter related..

Light came back on

codes are P0171 bank 1 lean

P1472 manufacturer specfic code

Expert:  Virtual Wrench replied 6 years ago.



The P0171 is for the O2 sensor and the other one was probably set because of the O2 code. Replacing the sensor should take care of it. Driver side front sensor
