When I unplug my tps it reads 100%. When its plugged in it scrambles % 's while the car is running even with the sensor off the tb.

Hows the oil pressure? God forbid, but could it be a reluctor wheel problem, maybe took out the thrust bearing if the converter wasnt spaced right. Just a thought. Had a similar problem on my brothers car and thats what it turned out to be.
Also could easily be an electrical gremlin. Bad ground, loose connection etc..

Have you tried swapping the tps?

Yes and PCM. Same problem. Thats why we were thinking harness.

possible ground connection to the harnesses? I had the same problem, the car would not idle, until I added a retarded amount of fuel and then it would idle at 2k+ rpms. Found a loose ground wire on the back of the DS head and everything was fine. I didnt have any funny TPS readings but I think it was the coil ground that was making it run funny.

Well installed the harness back on the car and it starts up and runs...lol. I have no idea what it was. All I did was un-pin all the **** I was not using anymore.

O.k. issue is back. With my TPS unplugged its still jumping all over the place. How is that possible? What other sensors run off the same circuit?

I spent thousands on my Kenwood ces displayed Paxton supercharged firehawk one the pins in the tps got shoved out of the connector female side we put another male harnesses. Very frustrating

5w20 has a good idea, if ya unpinned crap and it was fine for a lil the problem could be in there

It is still the same issue. All the pins are in, double checked them. I am just going to re-pin the tps and get a new pigtail.

check if the PCM is sending the correct signal to the gray wire

check and see if the tps is sending the correct signal to the pcm through the dark blue wire

make sure the ground side is ok (black wire)

check splice 118, 116 and 119 for damage


see if you can separate the wires from the connector and plug them in directly to the TPS without the connector. Everything might look ok but the pin tension could be bad.

sorry i couldn't find a smaller pic

A long time ago on an lt1 I had a ICM shorting out thru the connector at the icm, everything looked ok, but somehow was shorting out inside it, major pain in the *** to figure out, I'd just pin in a new tps with nothing spliced into it.

Pinned new TPS wires and problem is gone.

Have the car re-tuned, change the wastegate spring and roll the rear fenders. Should be good to go.
