OK Redrotarty.

1, Warm up the engine.

2. Make sure all electricals off.

3. You have to get access to the ECU or the wires from the TPS and connect your voltmeter to 3F (black with green stripe) or 3G (green with red stripe) terminal.

4. Make sure your fast idle cam has seperated (not effecting setting).

5. With throttle closed should be 0.75-1.25V on 3F and 0.1-0.7V on 3G. If not loosen the screws and rotate the TPS until the reading is right in the middle.

6. At full throttle it should be 4.8-5.0V and 4.2-4.6.

7. Check range is from about 1.0 to 5.0V on 3F and 0.4 to 4.3V on 3G.

Thats it! The book says if you still have trouble you have to change the TPS. Have a great day!
