Default Re: 2001 SL1 High Idle Problem

So, live-data is telling you the TPS reading isn't consistent.

By "circuit" I was meaning the TPS itself and the wiring from it to the PCM, including all connectors, and the PCM itself. In addition, the mechanical "circuit" consisting of the TB blade, shaft, shaft stop, return spring, and the arm that contacts the TPS are all possibilities for the TP reading not returning consistently to the same point. (TPS itself,of course, but that has already been changed a couple of times, right?)

Maybe you have just bought several poor TPS units, but I think that is unlikely. I would checked everything else a lot more before throwing another TPS at it.

REWARD EXCELLENCE!
