## DTC Troubleshooting: P1361 (8-2), P1362 (8-1)

DTC P1361 (8-2): | TDC Sensor Intermittent Interruption

1. | Reset the ECM/PCM.

2. | Start the engine. Is DTC P1361 and/or P1362 indicated? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the TDC sensor and at the ECM/ PCM.n

3. | Turn the ignition switch OFF.

4. | Disconnect the TDC sensor 3P connector.

5. | Turn the ignition switch ON (II).

6. | Measure voltage between the TDC sensor 3P connector terminal No. 3 and body ground. Is there battery voltage? YES - Go to 7. NO - Repair open in the wire between the PGM-FI main relay 1 and the TDC sensor.n

7. | Measure voltage between the TDC sensor 3P connector terminal No. 1 and body ground. Is there about 5 V? YES - Go to 8. NO - Go to 10.

8. | Measure voltage between the TDC sensor 3P connector terminals No. 2 and No. 3. Is there battery voltage? YES - Go to 9. NO - Repair open in the wire between the TDC sensor and G101.n

9. | Substitute a known-good TDC sensor and recheck. Is DTC P1361 and/or P1362 indicated? YES - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/ PCM.n NO - Replace the original TDC sensor.n

10. | Measure voltage between ECM/PCM connector terminal A26 and body ground. Is there about 5 V? YES - Repair open in the wire between the ECM/PCM (A26) and TDC sensor.n NO - Go to 11.

11. | Turn the ignition switch OFF.

12. | Disconnect the negative cable from the battery.

13. | Disconnect ECM/PCM connector A (31P).

14. | Check for continuity between ECM/PCM connector terminal A26 and body ground. Is there continuity? YES - Repair short in the wire between the ECM/PCM (A26) and the TDC sensor.n NO - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/ PCM.n
