Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Start the engine, and let it idle for 10 seconds.
- Check the CKP NOISE in the DATA LIST with the HDS. Are 0 counts indicated? YES -Go to step 7 . NO -Go to step 5.
- Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters: ENGINE SPEED VSS
- Check the CKP NOISE count in the DATA LIST with the HDS. Are 0 counts indicated? YES -Go to step 7. NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the ECM/PCM.
- Check for poor connections or loose terminals at these locations: CKP sensor ECM/PCM Engine ground Body ground Are the connections and terminals OK? YES -Go to step 8. NO -Repair or replace the connections or the terminals, then go to step 11 .
- Remove the cam chain case (see «CAM CHAIN REMOVAL»(ref-290827-S01491762362008072200000) ), then check for damage on the CKP sensor pulse plate. Is the pulse plate damaged? YES -Replace the CKP sensor pulse plate (see «CKP PULSE PLATE REPLACEMENT»(ref-290827-S20457298242008072200000) ), then go to step 11 . NO -Go to step 9.
- Turn the ignition switch to LOCK (0).
- Replace the CKP sensor (see «CKP SENSOR REPLACEMENT»(ref-355245-S37403578082010012100000) ).
- Turn the ignition switch to ON (II).
- Reset the ECM/PCM with the HDS.
- Clear the CKP pattern with the HDS.
- Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) ).
- Do the CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN»(ref-290833-S05169572102008072200000) ).
- Start the engine, and let it idle for 10 seconds.
- Check for Temporary DTCs or DTCs with the HDS. Is DTC P0339 indicated? YES -Check for poor connections or loose terminals at the CKP sensor and the ECM/PCM, then go to step 1 . NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
