P001200 Camshaft Position "A" - Timing Over-Retarded Bank 1 Intake valve timing is stuck at a certain value when in the retard range (2 trip detection logic).

  • Valve timing

  • Camshaft timing oil control valve assembly

  • Camshaft timing gear assembly

  • Oil control valve filter

  • ECM

 Comes on DTC stored SAE Code: P0012

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, camshaft timing oil control valve assembly and VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller 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 a VVT controller stuck malfunction and stores a DTC.


DTC P001100 (Advanced Camshaft Timing) is subject to 1 trip detection logic.

DTC P001200 (Retarded Camshaft Timing) is subject to 2 trip detection logic.

These DTCs indicate that the VVT controller cannot operate properly due to a camshaft timing oil control valve assembly malfunction or the presence of foreign matter in the camshaft timing oil control valve assembly.

    Tech Tips


    • If P001100 was output:

      Clear the DTC without using the GTS.

    • If P001200 was output:

      Clear the DTC using the GTS.

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

  6. Turn the power switch on (IG) [A].

    Tech Tips


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

    • If the judgment result is ABNORMAL, the system is malfunctioning.

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

  17. With the engine running, accelerate the vehicle to 75 km/h (46 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.

    Tech Tips

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

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

  19. Enter the following menus: Powertrain / Engine / Trouble Codes [H].

  20. Read the pending DTCs.

    Tech Tips


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

    • If a pending DTCs are not output, perform the following procedure.

  21. Check the DTC judgment result again.

    Tech Tips


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

CAUTION / NOTICE / HINT

Tech Tips


  • DTC P001100 or P001200 may be stored when foreign matter in the engine oil is caught in 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 P001100 OR P001200)
