I went to AutoZone to get my check engine light looked at. They gave me a print out that says:
"The PCN has determined that a malfunction exits in the heater curcuit for oxygen sensor 1 in bank 1."
That kid couldn't give me any more info. He couldn't tell me which 02 sensor, where it was...
Help!!! I have confidence I can change it, but which one do I change and where is it located?
