The PCM in my 02 Ram with 4.7 liter engine has suddenly fried. My mechanic says the cam shaft position sensor is bad and may have caused the PCM to fry. Anyone else had this problem? Just wondering whether to throw money into this truck to fix this problem. Also one of the wiring harness connectors to the PCM melted and will have to be replaced. Total cost I'm looking at is around $1500 and the mechanic says he cannot guarntee the new PCM will not fry. I've no problems up to this point with this truck. The truck has 103,000 miles on it.
