Variable Valve Timing Actuator Position Sensor: Testing and Inspection

Intake Valve Timing Control Position Sensor
Intake valve timing control position sensors are located in the front of cylinder heads in both bank 1 and bank 2.
This sensor uses a Hall IC.

The cam position is determined by the intake primary cam sprocket concave (in three places). The ECM provides feedback to the intake valve timing control for appropriate target valve open-close timing according to drive conditions based on detected cam position.

INTAKE VALVE TIMING CONTROL POSITION SENSOR

1. Disconnect intake valve timing control position sensor harness connector.
2. Loosen the fixing bolt of the sensor.
3. Remove the sensor.




4. Visually check the sensor for chipping.




5. Check resistance as shown here.
6. If NG, replace intake valve timing control position sensor.
