Last two times I had my motorhome out,got an engine trouble code (throttle position sensor low voltage). Can anyone tell me what may be causing this? The first time the light would come on during acceleration and would go off after I was up to speed. On the last trip the light came on and stayed. I can crank engine and light will not come on.
Maybe a bad sensor or the wiring going to it with supply voltage. Might also be a bad ground somewhere on the ECM.Not hard for a tech. to measure voltabes and tell problem. One wire 4.5 volts,one wire verying voltage with foot pedal position,one wire ground 0 volts. Good Luck Mike
