DTC P0076: Intake Valve Control Solenoid Circuit Low: Description

The CVVT (Continuously Variable Valve Timing) system built on the camshaft helps the engine decrease the exhaust gas and increase engine power and fuel economy by changing the valve open/close timing of the intake camshaft continuously. The OCV (Oil-flow Control Valve), the main control part of the CVVT, changes the direction of the oil path through the CVVT by the duty control of the ECM and changes the open and close timing of the intake and exhaust valves.
