INSPECTION PROCEDURE

Tech Tips


  • DTC P0011 or P0012 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain set even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.

  • Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011 OR P0012)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Enter the following menus: Powertrain / Engine / DTC.

    5. Read the DTCs.

      Result
      Result Proceed to
      DTC P0011 or P0012 is output A
      DTC P0011 or P0012 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0011 or P0012 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine.

    3. Turn the tester on.

    4. Turn the A/C switch on.

    5. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).

    6. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the tester.

      Result
      Tester Operation Specified Condition
      0% Normal engine speed
      100% Engine idles roughly or stalls

      Tech Tips

      If the result is not acceptable, cool the engine and perform the Active Test again.

  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0011 OR P0012)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Start the engine and warm it up.

    6. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    7. Idle the engine for 3 minutes or more.

    8. Enter the following menus: Powertrain / Engine / DTC.

    9. Read the pending DTCs.

      Tech Tips


      • If a pending DTC is output, the system is malfunctioning.

      • If a pending DTC is not output, perform the following procedure.

    10. Repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      Tech Tips

      Depress the accelerator pedal by a large amount.

    11. Idle the engine for 3 minutes or more.

    12. Enter the following menus: Powertrain / Engine / DTC.

    13. Read the pending DTCs.

      Result
      Result Proceed to
      DTC is not output A
      DTC P0011 or P0012 is output B

      Tech Tips

      DTC P0011 or P0012 may be stored when foreign objects in engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.
