Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting any work.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the oil level.
- If low, add the manufacturer-recommended oil until it reaches the correct level.

3. Inspect and Replace the Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter.
Disconnect the electrical connector from the sending unit.
Use a wrench to remove the sending unit.
Install the new sending unit by reversing the removal process, ensuring it is tightened to the manufacturer’s specifications (usually around 20-25 ft-lb).
Reconnect the electrical connector.

4. Check and Replace Oil Filter (if necessary)

Locate the oil filter.
Use an oil filter wrench to remove the old filter.
Apply a light coat of new oil to the rubber gasket on the new filter.
Install the new oil filter, tightening it hand tight plus a quarter turn.

5. Check for Oil Leaks

Start the engine and allow it to idle.
Inspect the area around the oil filter, sending unit, and oil pan for leaks.
If leaks are found, tighten connections or replace gaskets as needed.
