DTC P0335: CKP Sensor No Signal

NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).
  • Information marked with an asterisk (*1) applies to '09-11 models.
  • Information marked with an asterisk (*2) applies to '12 model.
  1. Turn the ignition switch to ON (II).
  2. Clear the DTC with the HDS.
  3. Start the engine.
  4. Check for Pending DTCs or Confirmed DTCs with the HDS.

    Is DTC P0335 indicated? 

    YES  -Go to step 5.

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

  5. Turn the ignition switch to LOCK (0).
  6. Disconnect the CKP sensor 3P connector.
  7. Turn the ignition switch to ON (II).
  8. Measure the voltage between CKP sensor 3P connector terminal No. 3 and body ground.

    Is there battery voltage? 

    YES  -Go to step 9.

    NO  -Repair open in the wire between the CKP sensor and PGM-FI main relay 1, then Go to step  19.

  9. Measure the voltage between CKP sensor 3P connector terminal No. 1 and body ground.

    Is there about 5 V? 

    YES  -Go to step 10.

    NO  -Go to step  11.

  10. Measure the voltage between CKP sensor 3P connector terminals No. 2 and No. 3.

    Is there battery voltage? 

    YES  -Go to step  17.

    NO  -Repair open in the wire between the CKP sensor and G101 (see ENGINE WIRE HARNESS ), then Go to step  19.

  11. Turn the ignition switch to LOCK (0).
  12. Jump the SCS line with the HDS.
  13. Disconnect PCM connector B (49P).
  14. Check for continuity between PCM connector terminal B45 and body ground.

    Is there continuity? 

    YES  -Repair short in the wire between the PCM (B45) and the CKP sensor, then Go to step  19.

    NO  -Go to step 15.

  15. Connect CKP sensor 3P connector terminal No. 1 to body ground with a jumper wire.

    Is there continuity? 

    YES  -Go to step  25.

    NO  -Repair open in the wire between the PCM (B45) and the CKP sensor, then Go to step  19.

  17. Turn the ignition switch to LOCK (0).
  18. Replace the CKP sensor (see CKP SENSOR REPLACEMENT ).
  19. Reconnect all connectors.
  20. Turn the ignition switch to ON (II).
  21. Reset the PCM with the HDS.
  22. Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).
  23. Do the CKP pattern learn procedure (see CKP PATTERN CLEAR/CKP PATTERN LEARN ).
  24. Check for Pending DTCs or Confirmed DTCs with the HDS.

    Is DTC P0335 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 DTCs or Confirmed DTCs are indicated, Go to the indicated DTC's troubleshooting. ■

  25. Reconnect all connectors.
  26. Update the PCM if it does not have the latest software (see PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
  27. Check for Pending DTCs or Confirmed DTCs with the HDS.

    Is DTC P0335 indicated? 

    YES  -Check for poor connections or loose terminals at the CKP sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, Go to step  1.

    NO  -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see PCM REPLACEMENT ). If any other Pending DTCs or Confirmed DTCs are indicated, Go to the indicated DTC's troubleshooting. ■
