So, about a week ago i got a CEL... I pulled out the scanner, and it said that the 02 sensor voltage was too low. so, i went back to checker and replaced the 02 sensor for free (under the 1 year warranty.. It'* a Bosch, and i bought it before i joined the forum
) Tthe CEL went away, and all seemed well.
A day or two after that, my "Traction Off" light came on when i started the car after school. I though i may have had a WSS go bad, but when i started the car up the next time, the light was off and Traction Control worked (yes, i tested it
Today, driving home both my CEL and my Traction light came on at the EXACT same time. Now, i have a hard time believing they would come on at the same time out of coincidence. So, my question is what would cause these to both come on at the same time?
I cleaned both my drivers and passenger side ground Bus about a month ago.
The only thing that came to my mind is the junkyard PCM i have in there. The first one i got from them was REALLY bad, the car would seem to hit a rev limiter at random RPMS at WOT. I think it may have had the wrong gear ratio. (come to think of it, idk if this one is the same as my real ratio either.. but it seems to shift fine.)
So... suggestions? thoughts?
