Solution

1. Preparation

Gather tools including an OBD-II scanner, mechanical oil pressure gauge, socket set, and wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level and Condition

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level. If low, add the recommended oil type (SAE 5W-20 or as specified in the owner’s manual).

3. Replace Oil and Oil Filter

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the drain plug using a socket wrench and allow the oil to drain completely.
Remove Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with fresh oil.
Install New Oil Filter:
- Thread the new oil filter onto the engine by hand until snug, then tighten it an additional 3/4 turn.
Add New Oil:
- Reinstall the drain plug and tighten it to the specified torque (check the owner's manual for the correct value).
- Fill the engine with the recommended amount of new oil through the oil filler cap.

4. Test Oil Pressure

Install Mechanical Gauge:
- Remove the oil pressure sending unit and install a mechanical oil pressure gauge.
Start Engine:
- Start the engine and monitor the gauge for oil pressure readings. Ensure it falls within the manufacturer’s specified range.
Turn Off Engine:
- If readings are low, further inspection of the oil pump may be required.

5. Inspect Oil Pump (if necessary)

If oil pressure is still low, remove the oil pan to access the oil pump.
Inspect the pump for wear or damage, and replace if necessary.
Reassemble all components and refill with oil.
