My engine light came on the other day and I got to autozone today and it was the ever so popular P0138. I did do a search on this forum (that is how I know this is a popular code
) but here is my question. They reset my engine light and I have driven it a few times and it never came back on. If it doesn't come back on should I just forget about it? I know from reading the threads I searched this could be a bad sensor or it could be a bad wire to the sensor, or it could be any other number of exhauste issues causing the jeep to run rich and messing with th voltage.
My code said "O2 sensor heater bank 1 sensor 2 shorted to voltage"
Thanks for the input.
