Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical accidents.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
If the oil level is low, add the manufacturer-recommended oil type until it reaches the full mark on the dipstick.
Replace the oil filler cap securely.

3. Replace Oil Filter (if needed)

Use an oil filter wrench to remove the old oil filter.
Lubricate the rubber gasket of the new oil filter with a bit of new oil.
Install the new oil filter, tightening it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the unit using a socket set.
Install the new sending unit, ensuring it is properly torqued to the manufacturer's specifications.
Reconnect the electrical connector.

5. Final Check

Reconnect the battery.
Start the engine and let it idle to check for leaks and listen for unusual noises.
Monitor the oil pressure warning light to ensure it does not illuminate again.
