Does the tps have to be mounted to the throttle body?

[Final777]

Hi this is final 777 again, how is everyone today. I've got a puzzlingly but intriguing question, it's probably going to sound pretty dumb....i have an 86 ranger 2.3 and my throttle position sensor has a bracket on the sensor, that screws in to a screw home on the throttle body itself i recently broke the screw off in it so i can't mount it anymore, but is that really a necessity. My truck is idiling very roughly but i believe the sensor h has gone bad as well. i also have a tiny wire on the female side of the sensor connector that is missing insulation, but it's not broken or served, but when i move the wires or the sensor itself it almost stalls on me. Please someone help!! Ty!

If possible, best course of action is:
* Drill out broken Screw\Bolt, rethread hole using one size larger.
* Use a little AntiSieze\Vaseline as a treat for next PoorBas'ard working on this vehicle.
* ReInsulate damaged wire with HeatShrink or splice in new HarnessSocket+PigTails.
* Replace bad TPS with new.

Have you tried to find a replacement throttle body?

And yes... TPS is necessary.

No ever i meant was if it a necessity for it to be mounted on the throttle body, but im assuming it is important and like an idiot i didn't bite the position of the tps when i took it off so im not sure how it goes back in it had slotted screw holes

I didn't note not bite sorry

I thought the tps was supposed to go under the cover sheet. Please include a cover sheet with your tps, umkay?

Yes. It must be mounted. It must be mounted properly and rigidly in order to sense the position if the throttle and report that position to the ECU. That is necessary for proper engine operation.

I think that's probably my best solution, the tps has slotted screw holes, and of course i didn't note exactly how it was positioned but i believe iCan measure tht resistance in the wiring I'm just not exactly sure how to go about that, do i need to turn the tps until 5 volts is acquired?

5v is the input voltage. You’re looking for as close to 1 volt as you can get on the output.

I had it a little wrong there, the lowest setting for closed throttle is 0.45 volts, which is where it should be at idle and at wot it's almost 5 volts but I've read in one book that i have, that if my tps is misadjusted that it will have to be replaced. I completed the signal adjustment, and she is running much better, but when she first starts up she almost chokes to death and almost dies on me, but after a few minutes she drives just fine
