4. Replace the oil filter using an oil filter wrench; ensure the old O-ring is removed.
5. Install a new oil filter, tightening by hand until snug.
6. Replace the drain plug and torque to manufacturer specifications (typically around 25 ft-lbs).
7. Refill the engine with the recommended oil type and quantity (usually 5W-30 or 0W-20, depending on specifications).
8. Start the engine and check for leaks around the oil filter and drain plug.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to remove the old sending unit.
4. Install the new oil pressure sending unit, tightening it to the manufacturer’s specifications.
5. Reconnect the electrical connector.

4. Final Check

Sub-steps:
1. Start the engine and let it idle for a few minutes.
2. Monitor the oil pressure warning light; it should extinguish if the issue is resolved.
3. Check the oil level again and top off if necessary.
