NOTE:
All testing procedures are made with engine at normal operating temperature.
Throttle Position Sensor (TPS) can be adjusted with the use of "Scan" tester or by the following procedure:
1) Install 3 jumper wires between TPS and TPS wiring harness connector.
2) 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.
3) Tighten screws and recheck readings. Turn ignition off. Remove jumper wires and reconnect harness connector to TPS.
