瀚慖f a condition is found, replace Q6 Camshaft Position Actuator Solenoid Valve.
6. Ignition OFF, swap the appropriate Camshaft Position Actuator Solenoid Valve with a Camshaft Position Actuator Solenoid Valve that is
operating correctly.
7. 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.
8. If all circuits/connections test normal, test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
Component Testing
1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
2. Test for 7-12 ohm between the control terminal 2 and the ignition terminal 1 of the Q6 Camshaft Position Actuator Solenoid Valve.
瀚慖f not within the specified range, replace the Q6 Camshaft Position Actuator Solenoid Valve.
3. Test for infinite resistance between each terminal and the Q6 Camshaft Position Actuator Solenoid Valve housing.
瀚慖f not the specified value, replace the Q6 Camshaft Position Actuator Solenoid Valve.
