Thirty peeps,
Strange problem:
Have voltage at plug to TPS (5 DCV as per spec).
Have continuity between all pins at ECU and ICM when throttle closed.
No continuity when throttle open -- so the switch is working. Have tested switch independently as well.
However, I have no voltage at run with the throttle closed between ground and pin #12 (closed throttle signal input to ICM).
Car runs fine when I'm on the gas because it's acting as it should be...but at closed throttle the thing idles really high because it isn't doing anything.
I'm so desperate to finally solve this high idle issue and this TPS no voltage to ICM thing is definitely the issue.
Does anyone know how that's even possible/what could be going on? I'm afraid to test any output/input voltage wise on the ECU because I don't accidentally fry something in there.
