Component Testing

  1. Ignition OFF, disconnect the harness connector at the Camshaft Position Actuator Solenoid Valve.
  2. Test for 5-13 Ω between the control terminal A and the low reference circuit terminal B of the Camshaft Position Actuator Solenoid Valve.
    • If not within the specified range, replace the Camshaft Position Actuator Solenoid Valve.
  3. Test for infinite resistance between each terminal and the Camshaft Position Actuator Solenoid Valve housing.
    • If not the specified value, replace the Camshaft Position Actuator Solenoid Valve.
  4. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.
