Solution

1. Preparation

Gather tools: OBD-II scanner, oil pressure gauge, socket set, and a clean rag.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level

Remove the dipstick and clean it with a rag.
Reinsert the dipstick fully, then remove it again to check the oil level.
If low, top off with the correct oil type as specified in the owner's manual.

3. Inspect for Leaks

Look under the vehicle and around the engine for any signs of oil leakage.
If leaks are found, identify the source (gaskets, seals, etc.) for repair.

4. Test Oil Pressure

Remove the oil pressure sending unit using a socket set.
Install the oil pressure gauge in place of the sending unit.
Start the engine and observe the gauge; it should read within the manufacturer's specifications (typically 25-65 psi at idle).

5. Replace Oil Filter and Oil

If the oil is dirty or contaminated, drain the old oil using an oil catch pan.
Replace the oil filter using an oil filter wrench.
Refill with new oil, ensuring the type and viscosity meet the manufacturer's recommendations.

6. Reinstall Components

Reinstall the oil pressure sending unit if it was removed.
Ensure all components are secured and there are no leaks before closing the hood.
