P1362
DTC P1361: Camshaft Position (CMP) Sensor B (TDC Sensor) Intermittent InterruptionDTC P1362: Camshaft Position (CMP) Sensor B (TDC Sensor) No Signal
1. Reset the ECM.
2. Start the engine.
Is DTC P1361 and/or P1362 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CMP sensor B (TDC sensor) and at the ECM.
3. Turn the ignition switch OFF.
4. Disconnect the CMP sensor B (TDC sensor) 3P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between CMP sensor B (TDC sensor) 3P connector terminal No.3 and body ground.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between the PGM-FI main relay 1 and the CMP sensor B (TDC sensor).
7. Measure voltage between CMP sensor B (TDC sensor) 3P connector terminal No.1 and body ground.
Is there about 5 V?
YES - Go to step 8.
NO - Go to step 10.
8. Measure voltage between CMP sensor B (TDC sensor) 3P connector terminals No.2 and No.3.
Is there battery voltage?
YES - Go to step 9.
NO - Repair open in the wire between the CMP sensor B (TDC sensor) and G101.
9. Substitute a known-good CMP sensor B (TDC sensor) and recheck.
Is DTC P1361 and/or P1362 indicated?
YES - Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM.
NO - Replace the original CMP sensor B (TDC sensor).
10. MEASURE VOLTAGE BETWEEN ECM CONNECTOR TERMINAL A26 AND BODY GROUND.
Is THERE ABOUT 5 V?
YES - REPAIR OPEN IN THE WIRE BETWEEN THE ECM (A26) AND CMP SENSOR B (TDC SENSOR).
NO- GO TO STEP 11.
11. TURN THE IGNITION SWITCH OFF.
12. DISCONNECT ECM CONNECTOR A (31P).
13. CHECK FOR CONTINUITY BETWEEN ECM CONNECTOR TERMINAL A26 AND BODY GROUND.
IS THERE CONTINUITY?
YES - REPAIR SHORT IN THE WIRE BETWEEN THE ECM (A26) AND THE CMP SENSOR B (DC SENSOR).
NO - UPDATE THE ECM IF IT DOES NOT HAVE THE LATEST SOFTWARE, OR SUBSTITUTE A KNOWN-GOOD ECM, THEN RECHECK. IF THE SYMPTOM/INDICATION GOES AWAY WITH A KNOWN-GOOD ECM, REPLACE THE ORIGINAL ECM.
