DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve (OCV) and VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure supplied to the VVT controller. Camshaft timing control is performed according to engine
operating conditions such as intake air volume, throttle valve position and engine coolant temperature.
The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller
regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative positions
of the camshaft and crankshaft are optimized, the engine torque and fuel economy improves, and the
exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve
timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.
This is how the target intake valve timing is verified by the ECM.

HINT:
If DTC P0011, P0012, P0021 or P0022 is present, check the VVT (Variable Valve Timing) system.
DESCRIPTION
Refer to DTC P0010 (See page ES-75).
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, the Oil Control Valve (OCV) and the VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure applied to the VVT controller. The VVT controller can advance or retard the intake camshaft.
If the difference between the target and actual intake valve timings is large, and changes in actual intake
valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and sets a DTC.
Example:
A DTC will be set when the following conditions 1), 2) and 3) are met:
1) The difference between the target and actual intake valve timings is more than 5
CA (Crankshaft
Angle) and the condition continues for more than 4.5 seconds.
2) It takes 5 seconds or more to change the valve timing by 5
CA.

3) After above conditions 1) and 2) are met, the OCV is forcibly activated 63 times or more.
DTCs P0011 and P0021 (Advanced Cam Timing) are detected with 1 trip detection logic.
DTCs P0012 and P0022 (Retarded Cam Timing) are detected with 2 trip detection logic.
These DTCs indicate that the VVT controller cannot operate properly due to OCV malfunctions or the
presence of foreign objects in the OCV.
The monitor will not run unless the following conditions are met:
- The engine is warm (the engine coolant temperature is 75
C [167F] or more).
- The vehicle has been driven at more than 40 mph (64 km/h) for 3 minutes.
- The engine has idled for 3 minutes.

P0011, P0021:

If the difference between the target and actual camshaft timings is greater than the specified value, the
ECM operates the VVT actuator.
Then, the ECM monitors the camshaft timing change for 5 seconds.
