Hey there, yes I did a search already....but have a different question.
The voltage on a TPS sensor is supposed to be read as follows, and please correct me if I'm wrong:
Key on, put postive probe on middle wire of connector, and bottom wire is ground, at idle the voltage is supposed to be .5v and WOT is supposed to be 4.2v.
Now my question is I check my camaro the same way....but got 4.2v at idle and about .5v at WOT...The car runs good with no check engine light and everything seems normal.....but is this right??? let me know if you can help......thanks in advance.

I can confirm, you measure the voltage across A and B. I would set the TPS at 0.60 V for idle, and the full throotle voltage will come out to be whatever it can reach. It should be at least 4.0 V.
sweet, I will try that then....top wire positive at .60v and middle wire is ground....I didn't have a check engine light on but wanted to be sure.....
one more question though.......this is a spare TPS sensor I had sitting around....the one that was on my car had no slots for adjustment, it was a self zero-ing so to speak, this new one has slots on it for adjustment....is it the computer that self zeros or it the type of sensor....both sensors are from camaro's of course, but two different part numbers, I'm suspecting different years but everything seems to be working okay.
