Circuit/System Verification

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 GMC Yukon XL, 2018 GMC Yukon, 2018 Chevrolet Tahoe, 2018 Chevrolet Suburban, and 2018 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • The engine oil level and the oil pressure are critical to the correct operation of the system.
  • Engine oil condition has a major impact on the camshaft actuator system.
  • If a crankshaft or camshaft position sensor DTC is set, the scan tool camshaft position actuator output control will be disabled.
  1. Ignition - On / Vehicle - In Service Mode
  2. Verify DTC P0335, P0336, P0340, P0341 is not set.
    • Go to next step : If none of the DTCs are set 
  3. Verify the following conditions do not exist :
    • If a condition exists 

      Repair as necessary

    • Go to next step : If no condition exists 
  4. Engine - Idling
  5. Perform the scan tool control function : Camshaft Position Actuator - From 0 to 20° and back to 0°.
  6. Verify the scan tool parameter :
    • Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status = OK or Not Run
    • Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status = OK or Not Run
    • Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status = OK or Not Run
    • If not the specified state 

      Refer to Circuit/System Testing below

    • Go to next step : If the specified state 
  7. Perform the scan tool control function : Camshaft Position Actuator - From 0 to 20° and back to 0°.
  8. Verify the scan tool parameter : Camshaft Position Variance = Less than 2° - During each of the commanded states
    • If 2° or greater 

      Refer to Circuit/System Testing below

    • Go to next step : If less than 2° 
  9. Verify the scan tool parameter : Camshaft Position Variance = Less than 2°
  10. Perform the action while monitoring the parameter :
    • Wiggle the harness and connector : Q6 Camshaft Position Actuator Solenoid Valve
    • Wiggle the harness and connector : K20 Engine Control Module
    • If 2° or greater 

      Repair as necessary - Wiring / Terminal(s) / Electrical Connector(s)

    • Go to next step : If less than 2° 
  11. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

    Verify the DTC does not set.

    • If the DTC sets 

      Refer to Circuit/System Testing below

    • Go to next step : If the DTC is not set 
  12. All OK.
