Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P0083: Intake Valve Control Solenoid Circuit-High (Bank 2): General Description
The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the camshaft. This system controls the camshaft to provide the optimal valve timing for every driving condition. The PCM controls the Oil Control Valve (OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. The CVVT controller regulates the 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 over all driving conditions.
