If you do a search on TPS you will find the info you need.
There is a three wire connector on the TPS cable set with labels of A,B,C. B is ground. A is supply voltage and C is return voltage.
1. Turn the ignition on without starting the engine.
2. Measure the input voltage. It should be between 4.5 and 5.0
3. Mesure the output voltage.
4. Loosen the screws of the TPS
5. Adjust the output voltage to about 88% of the input voltage.
6. Tighten the screws.
7. Check voltages again.
If you are unable to meet this spec., replace the TPS. They are abailble from Autozone for less than the Stealership.
