DTC P1089, P1092: VVEL Control Shaft Position Sensor: Description
WARNING: This page is about a different car, the 2010 Infiniti G37. However, it is still accessible from the selected car via links, so may be relevant.
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.
