Looking for some input on my early 04. Truck is over charging, running around 17.7-14.8. Have put 2 new alt on it thinking faulty, new battery's. Truck is throwing 0108 map sensor voltage high, 0643 primary 5 volt supply circut high, 0642 sensor reference voltage 1 circut low. truck is also throwing 0480 fan control and 0483 fan speed, it has always thrown these 2, but never given me a problem. Also threw a govoner pressure sensor voltage too high but after clear'd has not came back. Any input greatly appreciated truck doesnt seem to run that great either. Thinking possibly pcm but don't have access to try one and can't afford to buy one and not fix the problem.
