DTC P0339: CKP Sensor Circuit Intermittent Interruption

1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine, and let it idle for 10 seconds.
4. 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.

5. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters:
   • ENGINE SPEED
   • VSS
6. Check the CKP NOISE 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 PCM.

7. 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 8.

   NO  -Repair the connections or terminals, then go to step  11.

8. Check for damage on the CKP sensor pulser plate (see CKP PULSE PLATE REPLACEMENT ).

   Is the pulser plate damaged? 

   YES  -Replace the CKP sensor pulser plate (see CKP PULSE PLATE REPLACEMENT ), then go to step  11.

   NO  -Go to step 9.

9. Turn the ignition switch to LOCK (0).
10. Replace the CKP sensor (see CMP SENSOR REPLACEMENT ).
11. Turn the ignition switch to ON (II).
12. Reset the PCM with the HDS.
13. Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).
14. Do the CKP pattern learn procedure (see CKP PATTERN CLEAR/CKP PATTERN LEARN ).
15. Start the engine, and let it idle for 10 seconds.
16. 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.
