Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
NOTE: You must complete the Circuit/System Verification before proceeding with Circuit/System Testing
  1. Ignition/Vehicle Off, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve, ignition On/vehicle in Service Mode.
  2. Verify a test lamp illuminates between the control circuit terminal 2 or B and ground when commanding the appropriate Camshaft Position Actuator Solenoid Valve On with a scan tool.
    • If the test lamp does not illuminate 
    1. Ignition/Vehicle Off, disconnect the harness connector at the K20 Engine Control Module.
    2. Test for less than 2 Ω in the control circuit end to end.
    • If 2 Ω or greater, repair the open/high resistance or short to ground in the circuit.
    • If less than 2 Ω, replace the K20 Engine Control Module.
    • If the test lamp illuminates 
  3. Ignition/Vehicle Off.
  4. Remove the appropriate Q6 Camshaft Position Actuator Solenoid Valve. Inspect the Camshaft Position Actuator Solenoid Valve and mounting area for the following conditions:
    • For a torn, restricted, incorrect positioned or missing screens at the Q6 Camshaft Position Actuator Solenoid Valve
    • For engine oil leaks between the oil sealing lands of the Q6 Camshaft Position Actuator Solenoid Valve
    • For oil seepage at the Q6 Camshaft Position Actuator Solenoid Valve connector
      • If a condition is found 

        Replace the Q6 Camshaft Position Actuator Solenoid Valve.

      • If a condition is not found 
  5. Exchange the suspected Q6 Camshaft Position Actuator Solenoid Valve with a Q6 Camshaft Position Actuator Solenoid Valve that is operating correctly.
    NOTE: This step is testing the mechanical operation of the camshaft position actuator solenoid valve that set the DTC.
  6. Engine Running.
  7. Command the appropriate camshaft position actuator from 0 degrees to 20 degrees and back to zero while observing the appropriate scan tool Intake/Exhaust Camshaft Position Variance parameters. The Intake/Exhaust Camshaft Position Variance should be less than 2 degrees in each of the commanded states.
    • If the Camshaft Position Variance parameter is greater than 2 degrees 

      Replace or repair the mechanical camshaft position actuator

    • If the Camshaft Position Variance parameter is less than 2 degrees 
  8. Test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
