Component Testing

  1. Measure the resistance of the CMP actuator solenoid valve assembly. Resistance should be between 8-15 ohms.
  2. Connect a fused jumper wire between the CMP actuator powertrain main relay fused supply circuit terminal A at the solenoid and B+. Connect a jumper wire to the camshaft phaser solenoid control circuit terminal B at the solenoid. Momentarily touch the jumper wire to ground. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.
    • If the spool valve inside the CMP actuator solenoid does not move, replace the CMP actuator solenoid.
  3. Inspect each CMP actuator solenoid valve assembly for the following:
    • Torn screens
    • Debris on the screens
    • Debris clogging the oil ports
    • Missing screens
    • Oil seepage at the solenoid connector pins
