1. Record all freeze data and any on-board snapshot with the HDS.
2. Clear the DTC with the HDS.
3. Start the engine, and let it idle 10 seconds.
4. Check the CKP NOISE count in the DATA LIST with the HDS.

YES - Go to step 7.

NO - Go to step 5.

5. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters:
- Engine speed
- Vehicle speed

6. Check the CKP NOISE count in the DATA LIST with the HDS.

Are 0 counts indicated?

YES - Go to step 7.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the ECM/PCM.

7. Check for poor or loose connections and terminals at these locations:
- CKP sensor
- ECM/PCM
- Engine ground
- Body ground

Are the connections OK?

YES - Go to step 8.

NO - Reconnect the connectors or terminals, then go to step 11.

8. Remove the cam chain case, and check for damage on the CKP sensor pulse plate.

Is the plate damaged?

YES - Replace the CKP sensor pulse plate, then go to step 11.

NO - Go to step 9.

9. Turn the ignition switch OFF.
10. Replace the CKP sensor.
11. Turn the ignition switch ON (II).
12. Reset the ECM/PCM with the HDS.
13. Clear the CKP pattern with the HDS.
14. Do the ECM/PCM idle learn procedure.
15. Do the CKP pattern learn procedure.
16. Start the engine, and let it idle 10 seconds.
17. Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?

YES - If DTC P0339 is indicated, check for poor connections or loose terminals at the CKP sensor 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.
