CVVT Oil Control Valve (OCV)

CVVT OIL CONTROL VALVE (OCV)

INSPECTION

FUNCTION AND OPERATION PRINCIPLE
The Continuously Variable Valve Timing (CVVT) system controls the amount of valve overlap by varying the amount of oil flow into an assembly mounted on each intake camshaft through PCM control of an oil control valve. This system uses two oil control valves, one on each bank. An Oil Temperature Sensor (OTS) is used to allow PCM monitoring of engine oil temperature. As oil is directed into the chambers of the CVVT assembly, the cam phase is changed to suit various performance and emissions requirements.

1. When camshaft rotates engine rotation-wise: Intake Advance/Exhaust Retard
2. When camshaft rotates counter engine rotation-wise: Intake- Retard/Exhaust- Advance
