I am not getting any codes but I put a OBD II tester on my car and it said that my TPS was at 17.6% with engine off and Idle and only goes to 90.5% full throttle with engine off. A new TPS is $32.00. I put the OBD II tester on my other cars{All Chevys} and their TPS go from 0.00% to 100%.



I tried to volt test it but I could not get it to work. Would I be able to get my money back if I got an new one but it only went from 17.6 to 90.5

Hi mate, you wouldn't be able to get your money back I don't think.

Have you had the ecu tested? I know I must sound like a broken record but I work for a specialist company and these problems I'm reading on this forum are very common to us on a daily basis.

Just a thought.

Goodluck.

Are you having some sort of drivability problem or is this something you just noticed playing around with the scanner???

I thought OBD II started at 96, not 94

Its something I noticed playing around with the scanner.
And OBD II started in 94 just like the air bags

In some instances the TPS will read as partially open. The throttle blade is slightly open even though the IAC controls the idle. When you put on a TPS you have to twist it a little to align the bolt holes. If you have no problems just ignore it.
