Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool down if it was recently running.

2. Check Oil Level

Remove the dipstick, clean it with a rag, and reinsert it fully.
Remove the dipstick again and check the oil level; add oil if low (refer to manufacturer specs).

3. Inspect for Leaks

Look for any oil leaks around the oil pan, oil filter, and oil lines.
If leaks are found, identify the source and proceed to repair as needed.

4. Replace Oil and Filter (if necessary)

Drain the old oil using a socket set to remove the oil drain plug.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and refill with the correct type and amount of new oil.

5. Test Oil Pressure

Remove the oil pressure sending unit using a socket set.
Install a mechanical oil pressure gauge in its place.
Start the engine and observe the oil pressure reading; it should be within the manufacturer's specifications.

6. Replace Oil Pressure Sending Unit (if necessary)

If the oil pressure is within spec but the light remains on, replace the oil pressure sending unit.
Reinstall the electrical connector and ensure it is secure.

7. Reassemble and Recheck

Reinstall any components removed during the inspection and testing.
Start the engine and monitor the oil pressure warning light for re-illumination.
