Camshaft Position Sensor

Print

OPERATION



The camshaft position sensor is installed on the front of the right cylinder head of the 5VZ-FE engine. The timing rotor has been integrated with the right bank camshaft timing pulley. While the camshaft rotates, the air gap between the protrusion on the timing rotor and the pick-up coil changes. This causes fluctuation in the magnetic field and generates a voltage signal in the pick-up coil.

TESTING



  1. Disconnect the sensor harness.
  2.  
  3. Measure the resistance between the sensor terminals. It should be between 835-1400 ohms.
  4.  
  5. If not within specifications, replace the sensor.
