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..
