Throttle Position Sensor Question

XXBULLETSXX said:

I'm not following you, do you mean that you adjust the voltage going to the TPS? If so, how do you do that? I basically played with it using the slop in the clearance holes for the screws which mount the TPS to the throttle body. But if there's an easier way please let me know.
Knowing my luck it will take an $800 program to do it really simply.

no, if your car if idling properly it is probably fine. On my 2000 and I think yours is the same , the TPS has 2 holes that are round for the screws to go through. On older Mustangs the TPS had holes that were elongated so the tps could rotate a little. If you install the tps and tighten it down it should be correct. I'm sorry if I confused you, you don't adjust the voltage going to the tps. You should have check the voltage coming from the tps ( that is what you would adjust, but they aren't really designed to be adjusted). I don't remember off the top of my head which wires but it sounds like you were checking the correct ones. The voltage reading should be below 1 volt at idle.
