P1089 OBD Code Definition:
P1089 VVEL Control Shaft Position Sensor Bank 1 Circuit
P1089 OBD Code Description:
– VVEL Control Shaft Position Sensor Bank 1 harness is open or shorted
– VVEL Control Shaft Position Sensor Bank 1 circuit poor electrical connection
– Faulty VVEL control module Symptoms – Engine Light ON (or Service Engine Soon Warning Light) P1089 OBD Code Description
VVEL (Variable Valve Event & Lift) is a system that controls valve event and valve lift continuously. Rotational movement of the drive shaft equipped with eccentric cam is transmitted to output cam via the rocker arm and two kinds of links to depress the intake valve. The Engine Control Module (ECM) decides the target valve lift according to the driving condition and sends the command 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 movement of the output cam by shifting the link supporting point. As a result, valve lift changes continuously to improve engine output and response.
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.
