Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the old oil into an appropriate container.
2. Replace the oil filter with a new one, ensuring the old filter gasket is removed as well.
3. Reinstall the drain plug and tighten it to the manufacturer’s specified torque (usually around 25-30 ft-lbs).
4. Fill the engine with the recommended grade and type of oil (check owner's manual for specifications).
5. Start the engine and let it run for a few minutes, then check for leaks around the oil filter and drain plug.

3. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. Locate the oil pressure sending unit on the engine, typically near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Use a wrench to remove the sending unit from the engine.
4. Install the new sending unit and tighten it to the manufacturer’s specifications.
5. Reconnect the electrical connector and ensure it is secure.
