With vehicles you basically set the TPS to read what the computer wants to see which should show approx. .5 at idle and 4.9 at WOT. Stock TPS sensors are not slotted so cannot be adjusted unless you dremel a slot. Too many other things to account for if you try resetting the factory set blade such as IAC, etc.

To read/test the TPS voltage either use a scan tool or you can use a volt meter at the TPS and test the dark blue wire for the voltage as stated above approx .5-4.9
