Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface with the engine off.
Allow the engine to cool down if it has been running.

2. Check and Top Off Engine Oil

Open the hood and locate the oil filler cap.
Remove the oil dipstick, clean it with a rag, and reinsert it fully.
Remove the dipstick again to check the oil level. If low, add the manufacturer-recommended oil through the oil filler cap.
Recheck the oil level to ensure it is within the acceptable range.

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten it an additional 3/4 turn.

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
Disconnect the electrical connector and remove the sending unit using a socket wrench.
Apply Teflon tape to the threads of the new sending unit and install it.
Reconnect the electrical connector.

5. Verify and Test Oil Pressure

Reconnect the battery if it was disconnected.
Start the engine and let it idle.
Use a mechanical oil pressure gauge to verify the oil pressure readings against manufacturer specifications.
Ensure the warning light is off during operation.
