My son replaced the PCM on the Cavalier and the car will not start.
My scanning tool shows a code PO122 and P1336. Do I have to enter a "learn procedure" for the PCM? The throttle positioning censor for the PO122 was replaced, and before the PCM was changed, that was the only code it had but the car would not start.
Any help is very appreciated!
have the same problem?
