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 for safety.

2. Check and Refill Engine Oil

Tools Required: Oil filter wrench, socket set, funnel.
Remove the oil filler cap and use the dipstick to check the oil level.
If low, add the appropriate oil type as specified in the owner’s manual until it reaches the correct level.

3. Change Oil and Oil Filter

Tools Required: Oil pan, socket set, oil filter wrench, torque wrench.
Place an oil pan under the oil pan and remove the drain plug with a socket wrench; allow the old oil to fully drain.
Remove the old oil filter using the oil filter wrench. Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter and torque it to the recommended specification (typically around 20-25 lb-ft).
Replace the drain plug and torque to the manufacturer’s specification (typically around 15-20 lb-ft).

4. Replace Oil Pressure Sending Unit

Tools Required: Socket set, wrench set.
Locate the oil pressure sending unit, usually found near the oil filter or on the engine block.
Disconnect the electrical connector and unscrew the sending unit using a socket or wrench.
Install the new sending unit and reconnect the electrical connector.

5. Final Steps

Refill with the appropriate amount of engine oil as specified in the owner’s manual.
Reconnect the negative battery terminal.
Start the engine and allow it to run for a few minutes, checking for leaks around the oil filter and drain plug.
