* Oil seepage at the CMP actuator solenoid connector



瀚慖f a condition is found, replace Camshaft Position Actuator Solenoid Valve.



7. Ignition OFF, swap the Camshaft Position Actuator Solenoid Valve with a Camshaft Position Actuator Solenoid Valve that is operating



correctly.



Note: This step is testing the mechanical CMP actuator for the camshaft that set the DTC.



8. Engine idling. Command the appropriate Camshaft Position Actuator from 0 degrees to 40 degrees and back to zero while observing the



appropriate scan tool Camshaft Position Variance parameters. The Camshaft Position Variance should be less than 2 degrees in each of the



commanded states.



瀚慖f greater than the specified value, replace the mechanical camshaft position actuator.



9. If all circuits/connections test normal, test or replace the Camshaft Position Actuator Solenoid Valve.



Component Testing



1. Ignition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve.



2. Test for 7-12 ohm between the control terminal 2 and the ignition terminal 1 of the solenoid.



瀚慖f not within the specified range, replace the Camshaft Position Actuator Solenoid Valve.



3. Test for infinite resistance between each terminal and the solenoid housing.



瀚慖f not the specified value, replace the Camshaft Position Actuator Solenoid Valve.
