  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

    Tech Tips


    • P0011 is output:

      Clear the DTC without using the GTS.

    • P0012 is output:

      Clear the DTC with using the GTS.

  4. Turn the power switch off and wait for at least 30 seconds.

  5. Turn the power switch on (IG) and turn the GTS on [A].

  6. Put the engine in inspection mode (maintenance mode).

  7. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].

    Tech Tips

    Park (P) is selected.

  8. Accelerate the vehicle to 60 km/h (37 mph) or more by depressing the accelerator pedal for 10 seconds or more [C].

    CAUTION:

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

    Tech Tips

    If the engine stops, further depress the accelerator pedal to restart the engine.

  9. Idle the engine for 100 seconds or more [D].

    Tech Tips

    Park (P) is selected.

  10. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [E].

  11. 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.

  12. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  13. Input the DTC: P0011 or P0012.

  14. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [F] through [H].

  15. Accelerate the vehicle to 60 km/h (37 mph) or more by depressing the accelerator pedal for 10 seconds or more [F].

    CAUTION:

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

  16. Idle the engine for 100 seconds or more [G].

    Tech Tips

    Park (P) is selected.

  17. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [H].

  18. 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.

  19. Check the DTC judgment result again.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tech Tips


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

  • Read freeze frame data using the GTS. 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 GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    5. Read the DTCs.

      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.

      Control the VVT Linear (Bank1)

    7. Check the engine speed while operating the camshaft timing oil control valve assembly using the GTS.

      OK
      GTS Operation Specified Condition
      0% Normal engine speed
      100% Engine idles roughly or stalls

      Tech Tips


      • Refer to "Data List / Active Test" [VVT OCV Duty #1 and VVT Change Angle #1].
