MONITOR DESCRIPTION

The ECM optimizes the intake valve timing using the Variable Valve Timing (VVT) system to control the intake camshaft. The VVT system includes the ECM, cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) and camshaft timing gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly. The camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) is operated to control the oil pressure supplied to the camshaft timing gear assembly based on this signal. The camshaft timing gear assembly can advance or retard the intake camshaft.

If the difference between the target and actual intake valve timing is large, and changes in the actual intake valve timing are small, the ECM interprets this as the camshaft timing gear assembly stuck malfunction and stores a DTC.

  • Example:
  • A DTC is stored when the following conditions are met:
    1. It takes 5 seconds or more to change the valve timing by 5°CA.
    2. After the above condition is met, the cam timing oil control solenoid assembly is forcibly activated for 9.5 seconds.

These DTCs indicate that the camshaft timing gear assembly cannot operate properly due to a camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) malfunction or the presence of foreign matter in the camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]).

TYPICAL MALFUNCTION THRESHOLDS

P0011 and P0021: Advanced Camshaft Timing

Both of the following conditions are met

-

Deviation of actual valve timing and target valve timing

More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit.

Valve timing

No change at advanced valve timing

P0012 and P0022: Retarded Camshaft Timing

Both of the following conditions are met

-

Deviation of actual valve timing and target valve timing

More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit.

Valve timing

No change at retarded valve timing

If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.

CONFIRMATION DRIVING PATTERN

HINT:

  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

    Click here

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

    Click here

  1. Connect the Techstream to the DLC3.
  2. Turn the engine switch on (IG).
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the engine switch off and wait for at least 30 seconds.
  6. Turn the engine switch on (IG) [A].
  7. Turn the Techstream on.
  8. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
  9. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [C].

    CAUTION:

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

  10. Idle the engine for 3 minutes or more [D].
  11. Enter the following menus: Powertrain / Engine / Trouble Codes [E].
  12. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  13. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  14. Input the DTC: P001100, P001200, P002100 or P002200.
  15. Check the DTC judgment result.

    Techstream 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

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system has a malfunction.
    • If the judgment result is INCOMPLETE, perform steps [F] through [H].
    • [A] to [E]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
  16. 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 [F].

    CAUTION:

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

    HINT:

    Depress the accelerator pedal by a large amount.

  17. Idle the engine for 3 minutes or more [G].
  18. Enter the following menus: Powertrain / Engine / Trouble Codes [H].
  19. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  20. Check the DTC judgment result again.

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system has a malfunction.
    • [A] to [H]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

  • DTC P001100, P001200, P002100 or P002200 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. That foreign matter may then be captured by the oil filter.
  • Read freeze frame data using the Techstream. 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.
