Anyone have a manual trans throttle pedal from an ALH TDI laying around? With harness disconnected, can you test the resistance between terminals 1 & 3 at idle and WOT?
I have an 18047/P1639 fault pedal sensor 1 int. signal. MVBs never show anything other than 0.0% for throttle position, but engine will rev to 1200 if pedal is depressed. Each wire to ECM has been load tested with a head light bulb. Connector pins are clean and look good. Appears to either be the pedal assembly or ECM. Neither are likely failures and both are expensive I think it's the pedal, but I want to be 100% sure.
Resistance between 1 & 3 on my pedal never changes no matter what position its in. This fault doesn't erase and exists whether the pedal is plugged in or not.
So close to getting my 4Runner on the road.. this pedal fault is one of the last major issues to sort out. Most other stuff is pretty minor. I'll post a build thread & pics soon.
