Variable Valve Timing Solenoid: Description and Operation

Electronic Engine Controls

The VCT oil control solenoid:

-

is an electrically controlled hydraulic valve that directs engine oil to the variable camshaft. Once the PCM transmits a signal, the solenoid moves a
valve spool, directing oil into the camshaft phaser cavity. This action changes valve timing by either inducing an advance or retard condition. The
camshaft is, thereby repositioned in relation to crankshaft timing and allows for optimum engine performance and lower emissions.
