Throttle Position Sensor Adjustment
Throttle Position Sensor (TPS) can be adjusted with the use of "Scan" tester or by the following procedure:
- Install 3 jumper wires between TPS and harness connector.
- Turn ignition on, engine off. Use digital voltmeter and connect to Dark Blue and Black wire terminals. With throttle at closed position, adjust TPS to obtain specified voltage.
- Tighten screws and recheck readings. Turn ignition off. Remove jumper wires and reconnect harness connector to TPS.
