P001200

Camshaft Position "A" - Timing Over-Retarded Bank 1

Intake valve timing is stuck at a certain value when in the retard range (1 trip detection logic).

  • Valve timing
  • Cam timing oil control solenoid assembly (for intake camshaft)
  • Camshaft timing gear bolt (intake camshaft timing oil control valve)
  • Camshaft timing gear assembly
  • ECM

Comes on

SAE: P0012

MONITOR DESCRIPTION

The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) system to control the intake camshaft. The VVT system includes the ECM, cam timing oil control solenoid assembly (for intake camshaft), camshaft timing gear bolt (intake camshaft timing oil control valve) and camshaft timing gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly (for intake camshaft). The camshaft timing gear bolt (intake camshaft timing oil control valve) 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:
  • DTC P001100 is stored when the following conditions "A" and "B" are met:
    1. It takes 5 seconds or more to change the valve timing by 5 deg(CA) (Condition "A").
    2. The above condition "A" is met, for 9.5 seconds or more (Condition "B").
  • DTC P001200 is stored when the following conditions "C" and "D" are met:
    1. It takes 5 seconds or more to change the valve timing by 5 deg(CA) (Condition "C").
    2. The above condition "C" is met, for 60 seconds or more (Condition "D").

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

    • If the judgment result shows INCOMPLETE, 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.

    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 shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

HINT:

  • DTC P001100 or P001200 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 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.
