Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface.
Disconnect the negative battery terminal for safety.

2. Check and Fill Engine Oil

Remove the oil filler cap.
Use a funnel to add the appropriate oil type (check owner’s manual for specifications).
Recheck the oil level with the dipstick and ensure it is at the proper level.
Reinstall the oil filler cap.

3. Inspect and Replace Oil Filter (if needed)

Use an oil filter wrench to remove the oil filter.
Apply a thin layer of new engine oil to the rubber gasket of the new oil filter.
Install the new oil filter, tightening it by hand until snug.

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter or engine block).
Disconnect the electrical connector and unscrew the sending unit using a socket.
Install the new sending unit and reconnect the electrical connector.

5. Test Oil Pressure

Install a mechanical oil pressure gauge in place of the sending unit.
Start the engine and observe the oil pressure readings; it should be within the manufacturer's specified range.
Turn off the engine and remove the gauge, reinstalling the sending unit if pressure is normal.
