MONITOR DESCRIPTION

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

If the difference between the target and actual exhaust valve timing is large, and changes in the actual exhaust valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and stores a DTC.

Example:





DTC P001400 (Advanced Camshaft Timing) is subject to 2 trip detection logic.

DTC P001500 (Retarded Camshaft Timing) is subject to 1 trip detection logic.

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

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

  6. Turn the ignition switch to ON.

  7. Turn the GTS on [A].

  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.

    Tech Tips


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

    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].

  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.

    Tech Tips

    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.

    Tech Tips


    • 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.

    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 the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

Tech Tips


  • DTC P001400 or P001500 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. This 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 P001400 OR P001500)
