Solution

1. Preparation

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

2. Change Oil and Filter

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and drain the old oil into the pan.
3. Replace the drain plug and tighten it to the manufacturer’s torque specification (typically around 20-25 lb-ft).
4. Remove the old oil filter using an oil filter wrench.
5. Lubricate the rubber gasket of the new oil filter with fresh oil and install it by hand.
6. Fill the engine with the recommended oil type and quantity (refer to the owner's manual, usually 5W-20 or 5W-30).

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to remove the sending unit and replace it with a new one.
4. Reconnect the electrical connector ensuring a secure fit.

4. Check for Leaks

Sub-steps:
1. Start the engine and allow it to idle.
2. Inspect the oil filter, drain plug, and oil pressure sending unit for leaks.
3. If no leaks are detected, turn off the engine after a few minutes.

5. Reconnect Battery

Reconnect the negative battery terminal and ensure it's secure.
