DTC P0339: CKP Sensor Circuit Intermittent Interruption
- 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:
- 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:
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
), 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 ), 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 ).
- 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 ).
- Do the CKP pattern learn procedure (see CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN ).
- 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.
