Circuit/System Testing

  1. Ignition Off and all vehicle systems Off, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 5 Ω between the low reference circuit terminal 1 and ground.
    • If 5 Ω or greater 
    1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K20 Engine Control Module.
      • If less than 5 Ω 
  3. Ignition On.
  4. Verify that a test lamp does not illuminate between the control circuit terminal 2nd ground.
    NOTE: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage. The current is too low to illuminate a test lamp. A voltage on the control circuit is normal.
    • If the test lamp illuminates 
    1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module, ignition On.
    2. Test for less than 1 V between the control circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K20 Engine Control Module.
      • If the test lamp does not illuminate 
  5. Remove the test lamp.
  6. Verify the scan tool parameters listed below do not display Malfunction when commanding the Camshaft Position Actuator Solenoid Valve On with a scan tool:
    • Intake Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status
    • Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status
    • Intake Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
    • Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
    • If Malfunction is displayed 
    1. Ignition 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 Malfunction is not displayed 
  7. Test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
