FUNCTION AND OPERATION PRICIPLE

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
