DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, camshaft timing oil control valve assembly and 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 camshaft timing gear assembly. 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 camshaft timing oil control valve assembly, based on the signals transmitted from several sensors. The camshaft timing gear assembly regulates the intake camshaft angle using oil pressure through the camshaft timing oil control valve assembly. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve timing using signals from the VVT sensor and crankshaft position sensor, and performs feedback control. This is how the target intake valve timing is verified by the ECM.
DTC No.

MONITOR DESCRIPTION
This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly (for intake side) circuit. If the oil control valve duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.

CONFIRMATION DRIVING PATTERN
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Clear DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page
).
-
Turn the ignition switch off and wait for at least 30 seconds.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Wait 5 seconds.
-
Enter the following menus: Powertrain / Engine / Trouble Code.
-
Read pending DTCs.
HINT:
-
If a pending DTC is output, the system is malfunctioning.
-
If a pending DTC is not output, perform the following procedure.
-
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
-
Input the DTC: P0010 or P0020.
-
Check the DTC judgment result.
