P0440 ANDP0452 ON 02 SILVERADO HOW CAN I REPAIR THIS WHAT VOLTAGE SHOULD THE PCM CARR
HAVE REPLCED PCM ONCE
Guess what... you will be replacing it again too. You won't be repairing the PCM yourself. I'm an electronic engineer and have a lot of test equipment and I couldn't do it at home.
You do need to check for bad or corroded electrical connections in the truck harness that may have caused the failure.
