Solution

1. Preparation

Gather tools: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, and rags.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Add Oil

Remove the dipstick, wipe it clean, reinsert, and then remove it again to check the oil level.
If the oil level is low, add the appropriate type and grade of oil as specified in the owner’s manual.

3. Inspect Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter.
Disconnect the electrical connector from the unit.
Remove the sending unit using the appropriate socket.
Install the new sending unit, ensuring it is tightened to the manufacturer's specifications (generally around 15-20 ft-lbs).

4. Test Oil Pressure

Remove the oil pressure sending unit and install the mechanical oil pressure gauge.
Start the engine and allow it to reach normal operating temperature.
Record the oil pressure reading; it should be within the manufacturer's specified range (typically 20-60 psi depending on the engine).

5. Replace Oil Filter (if necessary)

If the oil filter appears clogged or is due for a change, replace it.
Use an oil filter wrench to remove the old filter, lubricate the rubber gasket of the new filter with engine oil, and install the new filter by hand until snug.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and check for any leaks around the oil filter and sending unit.
Test drive the vehicle to ensure the oil pressure warning light remains off.
