Study Guide and General Description

Study The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. Study This system controls the intake camshaft to provide the optimal valve timing for every driving condition. Study The ECM controls the Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. Study The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, 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 and DTC Description

If there is a delay between the target angle and the real angle over 5 times,ECM sets DTC P0024.
