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.

Circuit/System Description

The camshaft position actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is

operating. The camshaft position actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the camshaft position

actuator solenoid duty cycle by controlling the amount of solenoid ON time. The camshaft position actuator solenoid controls the advance or the

retard of each camshaft. The camshaft position actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
