PROCEDURE:
1. Install three jumper wires between the TPS and the harness connector (or use a "Scan" tool.)
2. With the ignition ON and throttle closed, use a digital voltmeter connected to terminals "B" and "C" (or select TPS with "SCAN" tool), adjust the TPS so output voltage is 0.38-0.42 volts (middle of the operating range).
3. Tighten the screws, recheck the reading to verify the adjustment has not changed.
4. With the ignition OFF, remove the jumper wires and connect the harness to the TPS.
