WARNING: This page is about a different car, the 2019 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

The engine oil level and condition is critical to the correct operation of the system.

  1. Ignition - On / Vehicle - In Service Mode
  2. Verify there are no DTCs set related to the following system/component:
    • B35B Engine Oil Level Sensor
    • B37B Engine Oil Pressure Sensor
    • B37 Engine Oil Pressure Switch
    • Go to next step: If no other DTCs are set 
  3. Verify the condition does not exist:
    • Low Engine Oil Level
    • Dirty or contaminated oil
    • If a condition exists 

      Repair as necessary

    • Go to next step: If no condition exists 
  4. Perform the scan tool control function:Engine Oil Pressure Control Solenoid Valve - Low Pressure - High Pressure

    Verify the scan tool parameter:

    • Engine Oil Pressure Control Solenoid Valve Control Circuit Low Voltage Test Status = OK or Not Run
    • Engine Oil Pressure Control Solenoid Valve Control Circuit Open Test Status = OK or Not Run
    • Engine Oil Pressure Control Solenoid Valve Control Circuit High Voltage Test Status = OK or Not Run
    • If not the specified state 

      Refer to: Circuit/System Testing

    • Go to next step: If the specified state 
  5. Engine running.
  6. Perform the following steps:
    1. Increase the engine speed slowly to 1, 800 RPM.
      2. NOTE:

      Using the scan tool line graph function may make it easier to identify if the value changes.

    2. Perform the scan tool control function:Engine Oil Pressure Control Solenoid Valve - Low Pressure

      Verify the scan tool parameter: Engine Oil Pressure = Change is greater than 30 kPa (4 PSI)

      • If the change is 30 kPa (4 PSI) or less - Replace the component:Q44 Engine Oil Pressure Control Solenoid Valve
      • Go to next step: If the change is greater than 30 kPa (4 PSI)
  7. 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

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