Hey guys. I was driving down the road singing along to the N*SYNC cd in my cd player (not really) and my check engine light came on. It stayed on for about 1 or 2 minutes and then went off. It drove fine though, I didn't notice any difference. I got it home and ran the codes. It gave me 172, which the book tells me "sensor de gas oxigeno de escape calentado-la senal de voltaje indica un banco #1 rico"
....Then I flipped to the english side of the book......and it told me 'heated exhaust gas o2 sensor voltage signal indicates lean on bank #1
I just cleared the code to see if it would come back. I drove my normal routine for a couple more days, and nothing. Then one day it came back on. Again, it stayed on for a minute or 2, and then turned off.
If my motor was running lean, wouldn't both my o2's be telling me somthing, and not just the one side? Im a n00b.
