Variable Valve Timing Actuator Position Sensor: Description and Operation

COMPONENT PARTS

VVEL Control Position Sensor






VVEL control shaft position sensor (1) is placed on VVEL actuator sub assembly and detects the control shaft position angle.
A magnet is pressed into the arm on the edge of control shaft.
The magnetic field changes as the magnet rotates together with the arm resulting in the output voltage change of the sensor.
VVEL control module detects the actual position angle through the voltage change and sends the signal to ECM.
