DTC P0010: VTC Oil Control Solenoid Valve Malfunction

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).
  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS.
  3. Start the engine. Hold the engine speed at 3,000 rpm (min-1 ) without load (in Park or neutral) until the radiator fan comes on, then let it idle.
  4. Do the VTC TEST in the INSPECTION MENU with the HDS.
  5. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P0010 indicated? 

    YES  -Go to step 6.

    NO  -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/ PCM.

  6. Turn the ignition switch OFF.
  7. Disconnect the VTC oil control solenoid valve 2P connector.
  8. At the solenoid valve side, measure resistance between VTC oil control solenoid valve 2P connector terminals No. 1 and No. 2.

    Is there 6.75-8.25 Ω at room temperature? 

    YES  -Go to step 9.

    NO  -Go to step  14.

  9. Check for continuity between VTC oil control solenoid valve 2P connector terminal No. 1 and body ground.

    Is there continuity? 

    YES  -Go to step 10.

    NO  -Repair open in the wire between the VTC oil control solenoid valve and G101; A/T model (see ENGINE WIRE HARNESS (A/T) ), M/T model (see ENGINE WIRE HARNESS (M/T) ), then go to step  15.

  10. Jump the SCS line with the HDS.
  11. Disconnect ECM/PCM connector C (44P).
  12. Check for continuity between ECM/PCM connector terminal C23 and body ground.

    Is there continuity? 

    YES  -Repair short in the wire between the ECM/ PCM (C23) and the VTC oil control solenoid valve, then go to step  15.

    NO  -Go to step 13.

  13. Check for continuity between VTC oil control solenoid valve 2P connector terminal No. 2 and ECM/PCM connector terminal C23.

    Is there continuity? 

    YES  -Go to step  22.

    NO  -Repair open in the wire between the ECM/ PCM (C23) and the VTC oil control solenoid valve, then go to step  15.

  14. Replace the VTC oil control solenoid valve (see VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION  ).
  15. Reconnect all connectors.
  16. Turn the ignition switch ON (II).
  17. Reset the ECM/PCM with the HDS.
  18. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
  19. Do the VTC TEST in the INSPECTION MENU with the HDS.
  20. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P0010 indicated? 

    YES  -Check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step  1.

    NO  -Go to step 21.

  21. Monitor the OBD STATUS for DTC P0010 in the DTCs MENU with the HDS.

    Does the screen indicate PASSED? 

    YES  -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step  20, go to the INDICATED DTC'S TROUBLESHOOTING .

    NO  -If the screen indicates FAILED, check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step  1. If the screen indicates NOT COMPLETED, go to step  19.

  22. Reconnect all connectors.
  23. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or substitute a known- good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).
  24. Do the VTC TEST in the INSPECTION MENU with the HDS.
  25. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P0010 indicated? 

    YES  -Check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  24. If the ECM/PCM was substituted, go to step  1.

    NO  -Go to step 26.

  26. Monitor the OBD STATUS for DTC P0010 in the DTCs MENU with the HDS.

    Does the screen indicate PASSED? 

    YES  -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or DTCs were indicated in step  25, go to the INDICATED DTC'S TROUBLESHOOTING .

    NO  -If the screen indicates FAILED, check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  24. If the ECM/PCM was substituted, go to step  1. If the screen indicates NOT COMPLETED, go to step  24.
