Variable Valve Timing Actuator Position Sensor: Description and Operation

COMPONENT PARTS


VVEL Control Shaft Position Sensor






VVEL control shaft position sensor detects the control shaft position angle.
A magnet is installed to the tip of the control shaft.
The magnetic field changes as the control shaft rotates. This changes output voltage of the VVEL control shaft position sensor.
VVEL control module detects the actual position angle through the voltage change and sends the signal to ECM.
