DTC Troubleshooting: P0339

DTC P0339 : CKP Sensor Circuit Intermittent Interruption

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information How to Troubleshoot the Fuel And Emissions Systems.


1. Problem verification (idling):

-1. Turn the ignition switch to ON (II).

-2. Clear the DTC with the HDS. How to Troubleshoot the Fuel And Emissions Systems

-3. Start the engine, and let it idle for 10 seconds.

-4. Monitor the OBD STATUS for DTC P0339 in the DTCs MENU with the HDS.





Does the HDS indicate FAILED?
-YES- The failure is duplicated. Go to step 3.
-NO- If the HDS indicates PASSED, go to step 2. If the HDS indicates NOT COMPLETED, keep idling until a result comes on.

2. Problem verification (test-drive):

-1. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters:
* ENGINE SPEED
* VEHICLE SPEED

-2. Monitor the OBD STATUS for DTC P0339 in the DTCs MENU with the HDS.





Does the HDS indicate FAILED?
-YES- The failure is duplicated. Go to step 3.
-NO- If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the PCM. If the HDS indicates NOT COMPLETED, retest and check the OBD STATUS again.

3. Connectors and terminals condition check:

-1. Check for poor connections or loose terminals at these locations:
* CKP sensor
* PCM
* Engine ground
* Body ground

Are the connections and terminals OK?
-YES- Go to step 4.
-NO- Repair the connections or terminals, then do the repair verification.

4. CKP pulse plate visual check:

-1. Remove the CKP sensor CKP Sensor Removal And Installation, and check for damage to the CKP pulse plate.

Is the pulse plate damaged?
-YES- Replace the CKP pulse plate Service and Repair, then do the repair verification.
-NO- Replace the CKP sensor CKP Sensor Removal And Installation, then do the repair verification.

Repair verification:

-1. Turn the ignition switch to LOCK (0).

-2. Reconnect all connectors.

-3. Turn the ignition switch to ON (II).

-4. Reset the PCM with the HDS How to Troubleshoot the Fuel And Emissions Systems.

-5. Do the PCM idle learn procedure PCM Idle Learn Procedure.

-6. Do the CKP pattern clear/CKP pattern learn procedure How to Troubleshoot the Fuel And Emissions Systems.

-7. Start the engine, and let it idle for 10 seconds, or test-drive the vehicle for several minutes under the freeze data conditions (same as step 2-1).

-8. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0339 indicated?
-YES- Check for poor connections or loose terminals at the CKP sensor and the PCM, then go to step 1.
-NO- Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
