Quote: What do the APP sensors read when you move the gas pedal with them hooked up as they should change. 5 volts at rest does not sound right. Ron
Sounds like its time for a new pedal. The voltage on sensor 1 goes in the opposite direction than sensor 2 does when the pedal is depressed.
Could that cause IAT,ECT,Ambient,fuel sensor A all to read 5V ?
Get out your manual and I would start with an easy sensor to get to like the IAT. Disconnect it and ground the signal return circuit. Look at the scan tool and see if the volts go to zero. If it does there is a problem with the sensor. If it stays the same, back probe the same circuit at the pcm connector with a T-pin. May have an internal problem with the PCM.
