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.

  • 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 camshaft timing oil control valve assembly is forcibly activated for 9.5 seconds or more.

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.

TYPICAL MALFUNCTION THRESHOLDS

P0011: 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: 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 (camshaft timing oil control valve assembly) for 9.5 seconds or more by applying and releasing oil pressure. Then, the ECM monitors the change in camshaft timing for 9.5 seconds.

CAUTION / NOTICE / HINT

HINT:

  • 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 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.
