DTC Troubleshooting: P0365, P0365
DTC P0365:
CMP Sensor B Circuit No Signal
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information Initial Inspection and Diagnostic Overview.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0365 indicated?
YES -
Go to step 5.
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at CMP sensor B and the ECM/PCM.�
5. Turn the ignition switch to LOCK (0).
6. Disconnect the CMP sensor B 3P connector.
7. Turn the ignition switch to ON (II).
8. Measure the voltage between CMP sensor B 3P connector terminal No. 3 and body ground.
Is there battery voltage?
YES -
Go to step 9.
NO -
Repair open in the wire between CMP sensor B and PGM-FI main relay 1, then go to step 18.
9. Measure the voltage between CMP sensor B 3P connector terminal No. 1 and body ground.
Is there about 5 V?
YES -
Go to step 10.
NO -
Go to step 11.
10. Measure the voltage between CMP sensor 3P connector terminals No. 2 and No. 3.
Is there battery voltage?
YES -
Go to step 16.
NO -
Repair open in the wire between CMP sensor B and G101; A/T, M/T, then go to step 18.
11. Turn the ignition switch to LOCK (0).
12. Jump the SCS line with the HDS.
13. Disconnect ECM/PCM connector C (49P).
14. Check for continuity between ECM/PCM connector terminal C31 and body ground.
Is there continuity?
YES -
Repair short in the wire between the ECM/PCM(C31) and CMP sensor B, then go to step 18.
NO -
Go to step 15.
15. Check for continuity between CMP sensor B 3P connector terminal No. 1 and ECM/PCM connector terminal C31.
Is there continuity?
YES -
Go to step 23.
NO -
Repair open in the wire between the ECM/PCM(C31) and CMP sensor B, then go to step 18.
16. Turn the ignition switch to LOCK (0).
17. Replace CMP sensor B CMP Sensor B Replacement.
18. Reconnect all connectors.
19. Turn the ignition switch to ON (II).
20. Reset the ECM/PCM with the HDS.
21. Do the ECM/PCM idle learn procedure ECM/PCM Idle Learn Procedure (M/T).
22. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0365 indicated?
YES -
Check for poor connections or loose terminals at CMP sensor B and the ECM/PCM, then go to step 1.
NO -
Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
23. Reconnect all connectors.
24. Update the ECM/PCM if it does not have the latest software ECM/PCM Update (M/T), or substitute a known-good ECM/PCM.
25. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0365 indicated?
YES -
Check for poor connections or loose terminals at CMP sensor B and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then recheck. If the ECM/PCM was substituted, go to step 1.
NO -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
