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 Engine Control Module.
5. If all circuits/connections test normal, test or replace the appropriate 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 Camshaft Position Actuator Solenoid Valve.
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 Camshaft Position Actuator Solenoid Valve housing.
瀚慖f not the specified value, replace the Camshaft Position Actuator Solenoid Valve.
