Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
NOTE:

The engine oil level and condition has a major impact on the engine oil pressure control system. Debris in the oil can interfere with the engine oil pressure control solenoid valve 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. Verify correct engine oil level and condition.
  2. Engine Running, increase and maintain the engine speed at 1, 800 RPM.
    3. NOTE:

    Selecting the scan tool line graph function may make it easier to identify Engine Oil Pressure changes.

  3. Verify the scan tool Engine Oil Pressure parameter changes greater than 30 kPa (4 PSI) when commanding the Engine Oil Pressure Control Solenoid On and Off.
    • If the parameter does not change 

      Replace the Q44 Engine Oil Pressure Control Solenoid.

    • Go to next step: If the parameter changes 
  4. 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.
  5. Verify the DTC does not set.
    • Go to next step: If the DTC is not set 
  6. All OK.
