than 1 V when commanded ON.



瀚慖f the circuit voltage does not correspond to the specified values, test the control circuit for an open/high resistance or a short to ground. If



the circuit tests normal, replace the K20 ECM.



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 5-12 ohm between the control terminal 1 and the low reference circuit terminal 2 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.
