Variable Valve Timing Solenoid: Description and Operation
Electronic Engine Controls
Variable Camshaft Timing (VCT) Oil Control Solenoid (5.4L 3V)
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.
For removal and installation, refer to Variable Camshaft Timing (VCT) Oil Control Solenoid - 5.4L See: Service and Repair.
