My Caliber cannot pass state inspection with the light on. We've taken it to a mechanic who said he found no problems with the car. We've tried taking the negative cable off for 30 minutes. We've tried pressing the accelerator three times with the key in the ON position. We've tried taking it to AutoZone, but they said they couldn't reset the codes.

It's pulling the following codes :: P0522, P0500, P161B
Again, the mechanic checked these out and found no issues.

Background :: The check engine light came on after having my battery replaced. The guy at AutoZone didn't tighten the cables down and the positive cable slipped off. The car lost electric power and the light has been on ever since.

The dealer wants $110 just to see us. Any ideas?

 

Sounds like it may have damaged the PCM, a dealer reflash may be the only way to fix it if that will even work. Might need replaced.
