8. Measure voltage between CMP sensor 3P connector terminal No. 3 and body ground.

Is there battery voltage?

YES - Go to step 9.

NO - Repair open in the wire between the CMP sensor and PGM-FI main relay 1 (FI MAIN), then Go to step 18.




9. Measure voltage between CMP sensor 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 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 the CMP sensor and G101,then Go to step 18.




11. Measure voltage between ECM connector terminal A6 and body ground.

Is there about 5 V ?

YES - Repair open in the wire between the ECM (A6) and the CMP sensor, 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 connector A (31P).




15. Check for continuity between ECM connector terminal A6 and body ground.

Is there continuity?

YES - Repair short in the wire between the ECM (A6) and the CMP sensor, then Go to step 19.

NO - Go to step 23.

16. Turn the ignition switch OFF.
17. Replace the CMP sensor.
18. Reconnect all connectors.
19. Turn the ignition switch ON (II).

YES - Check for poor connections or loose terminals at the CMP sensor and the ECM, then Go to step 1.

NO - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, Go to the indicated DTCs troubleshooting.

23. Reconnect all connectors.
24. Update the ECM if it does not have the latest software, or substitute a known-good ECM.
25. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0365 indicated?

YES - Check for poor connections or loose terminals at the CMP sensor and the ECM. If the ECM was updated, substitute a known-good ECM, then recheck. If the ECM was substituted, Go to step 1.

NO - If the ECM was updated, troubleshooting is complete. If the ECM was substituted, replace the original ECM. If any other Temporary DTCs or DTCs are indicated, Go to the indicated DTCs troubleshooting.
