P1089 INFINITI Meaning
VVEL (Variable Valve Event & Lift) is a system that continuously controls valve event and valve lift. The rotational movement of the drive shaft equipped with an eccentric cam is transmitted to the output cam via the rocker arm and two types of links to push the intake valve. The engine control module (ECM) determines the target valve lift based on driving conditions and sends the control signal to the VVEL control module. The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor and changes the output cam movement by shifting the link support point. As a result, valve lift continuously changes to improve engine power and response.
The VVEL control shaft position sensor (1) is placed on the VVEL actuator assembly and detects the position angle of the control shaft. A magnet is pressed into the arm on the edge of the control shaft.
The magnetic field changes when the magnet rotates with the arm, causing a change in the sensor’s output voltage. The VVEL control module detects the actual position angle through the voltage change and sends the signal to the ECM.
