Throttle Position Sensor (TPS)
- Disconnect TPS electrical connector. Turn ignition on. Using a DVOM, backprobe TPS harness connector between terminals "B" and "C".
- Voltmeter should read approximately 5 volts. If voltmeter reading is incorrect, test vehicle with DRB-II (C-4805 ). If voltmeter reading is correct, go to next step.
- Turn ignition off. Check for continuity between TPS terminal "B" and ground. If circuit is open, test vehicle with DRB-II (C-4805 ). If continuity is present, go to next step.
- Reconnect TPS electrical connector. Turn ignition on. Measure voltage between TPS terminal "A" and ground. Voltmeter should read approximately .5-1.0 volt.
- If voltmeter reading is correct, TPS is okay. If voltmeter reading is incorrect, attempt to adjust TPS. If TPS cannot be adjusted within specification, replace TPS.
