General Description

Study Guide for The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. This system controls the intake camshaft to provide the optimal valve timing for every driving condition. The ECM controls the Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature.Study Guide The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result,Study the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.

Study Guide DTC Description

If there is a delay between the target angle and the real angle over 5 times,ECM sets DTC P0014.
