Re: tps sensor will not go over 3 volts,wot. problems?
What specific numerical code are you getting?
Have you verified you have a constant 5.0V between the black and gray wires in the harness connector, with the connector off the sensor?
Have you verified the closed throttle voltage, the WOT voltage between the black and blue wires with the harness connector on the sensor, and when you slowly rotate the blades open, does the voltage slowly increase, with no spikes or dropouts? Jiggle the harness wires to see if it causes intermittent changes in the readings.

Re: tps sensor will not go over 3 volts,wot. problems?
7 years later but hope to revive this. I have a 95lt1 a4. I replaced the tps on my stock tb but it intermittently cause an engine code and the bad shifting symptoms. Since it's brand new I assume it's the way I installed it that is causing these issue. Any input on how to adjust it would be great. Thanks
