The CVVT Oil Control Valve (OCV) which supplies the engine oil to the
cam phaser or runs out the engine oil from the cam phaser in accordance
with the ECM PWM (Pulse With Modulation) control signal, the CVVT Oil
Temperature Sensor (OTS) which measures the engine oil temperature,
and the Cam Phaser which varies the cam phase by using the hydraulic
force of the engine oil.
