2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.

2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.

瀚慖f the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal and the

ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.

3. Connect a DMM, set on the diode setting, between the control circuit terminal 2 and ground. The voltage should be greater than 2 V.

瀚慖f the DMM displays OL, test the control circuit for a short to voltage or an open/high resistance. If the circuit/connections test normal,

replace the K20 Engine Control Module.

瀚慖f less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control

Module.

4. Command the Camshaft Position Actuator Solenoid Valve ON and OFF with a scan tool. The DMM should transition from greater than 2 V

when commanded OFF to less than 1 V, when commanded ON.

瀚慖f the circuit voltage does not correspond to the specified values, replace the K20 Engine Control Module.

5. If all circuits/connections test normal, test or replace the appropriate 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.
