Solution

1. Preparation

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

2. Replace Engine Oil

- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new filter, tightening it by hand.
Step 3: Refill with new oil.
- Replace the drain plug and torque it to the manufacturer's specifications (typically around 25 Nm).
- Use a funnel to add the recommended type and amount of oil to the engine.

3. Replace Oil Pressure Sending Unit (if faulty)

Step 1: Locate the oil pressure sending unit.
- It is typically located near the oil filter or on the engine block.
Step 2: Disconnect the electrical connector from the sending unit.
Step 3: Use a socket to remove the old sending unit.
Step 4: Install the new sending unit and reconnect the electrical connector.

4. Final Checks

Start the engine and allow it to reach operating temperature.
Check for leaks around the oil filter and drain plug.
Monitor the oil pressure warning light to ensure it remains off.
