Circuit/System Verification

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. 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 camshaft position actuator system. Verify that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic.
    • The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position actuator solenoid and the mechanical camshaft actuator operation. Inspect for dirty or degraded crankcase oil. The engine may require an oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life Remaining parameter. Advise the customer an oil change may be required.
  1. Ignition On.
  2. Verify the correct engine oil level and pressure. Refer to Oil Pressure Diagnosis and Testing
    • If the oil level and the oil pressure are not correct  

      Repair as necessary

    • If the oil level and the oil pressure are correct  
    3. NOTE:
