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 OFF.
6. Disconnect the CMP sensor B 3P connector.
7. Turn the ignition switch ON (II).
8. Measure 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 voltage between CMP sensor B 3P connector terminal No. 1 and body ground.
Is there about 5V?
YES - Go to step 10.
NO - Go to step 11.
10. Measure voltage between CMP sensor B 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, then go to step 18.
11. Measure voltage between ECM/PCM connector terminal A6 and body ground.
Is there about 5 V?
YES - Repair open in the wire between the ECM/PCM (A6) and CMP sensor B, then go to step 18.
NO - Go to step 12.
12. Turn the ignition switch OFF.
13. Jump the SCS line with the HDS.
14. Disconnect ECM/PCM connector A (31P).
15. Check for continuity between ECM/PCM connector terminal A6 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM/PCM (A6) and CMP sensor B, then go to step 18.
NO - Go to step 23.
16. Turn the ignition switch OFF.
17. Replace CMP sensor B.
18. Reconnect all connectors.
19. Turn the ignition switch ON (II).
20. Reset the ECM/PCM with the HDS.
21. Do the ECM/PCM idle learn procedure.
22. Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P0365 is indicated, check for poor connections or loose terminals at CMP sensor B and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO - Troubleshooting is complete.
23. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.
24. Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P0365 is indicated, check for poor connections or loose terminals at CMP sensor B and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.
