DTC P0365, P0369, P1361, P1362: CMP Sensor B No Signal (2004 model); CMP Sensor B Circuit Intermittent Interruption (2004 model); CMP Sensor B Circuit Intermittent Interruption (2002-2003 models); CMP Sensor B No Signal (2002-2003 models);

NOTE:
  • Information marked with an asterisk (*) applies to 2004 model.
  • Information marked with double asterisk (**) applies to 2002-2003 models.
  1. Reset the ECM/PCM (see ECM/PCM RESET (2002-2004 MODELS) ).
  2. Start the engine.

    Is DTC P1361** (P0365)* and/or P1362** (P0369)* indicated? 

    1. YES -  Go to step 3.
    2. NO -  Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at CMP sensor B and the ECM/PCM.
  3. Turn the ignition switch OFF.
  4. Disconnect the CMP sensor B 3P connector.
  5. Turn the ignition switch ON (II).
  6. Measure voltage between CMP sensor B 3P connector terminal No. 3 and body ground.

    Is there battery voltage? 

    1. YES -  Go to step 7.
    2. NO -  Repair open in the wire between PGM-FI main relay 1 (FI MAIN) and CMP sensor B.
  7. Measure voltage between CMP sensor B 3P connector terminal No. 1 and body ground.

    Is there about 5 V? 

    1. YES -  Go to step 8.
    2. NO -  Go to step  10.
  8. Measure voltage between CMP sensor B 3P connector terminals No. 2 and No. 3.

    Is there battery voltage? 

    1. YES -  Go to step 9.
    2. NO -  Repair open in the wire between CMP sensor Band G101.
  9. Substitute a known-good CMP sensor B and recheck.

    Is DTC P1361 ** (P0365)* and/or P1362** (P0369)* indicated? 

    1. YES -  Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see HOW TO UPDATE THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see ECM/PCM REPLACEMENT  ).
    2. NO -  Replace original CMP sensor B (see CMP SENSOR B REPLACEMENT  ).
  10. Measure voltage between ECM/PCM connector terminal A26 and body ground.

    Is there about 5 V? 

    1. YES -  Repair open in the wire between the ECM/PCM (A26) and CMP sensor B.
    2. NO -  Go to step 11.
  11. Turn the ignition switch OFF.
  12. Disconnect ECM/PCM connector A (31P).
  13. Check for continuity between ECM/PCM connector terminal A26 and body ground.

    Is there continuity? 

    1. YES -  Repair short in the wire between the ECM/PCM (A26) and CMP sensor B.
    2. NO -  Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see HOW TO UPDATE THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see ECM/PCM REPLACEMENT  ).
