Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type and grade of engine oil specified in the owner’s manual.
Recheck the oil level after adding oil and ensure it is within the safe range.

3. Inspect and Replace Oil Filter

Locate the oil filter; use an oil filter wrench to remove it.
Apply a thin layer of oil to the rubber gasket on the new filter.
Install the new oil filter by hand-tightening it, then follow up with a quarter turn with the wrench.
Ensure the old filter's rubber gasket is removed to prevent leaks.

4. Test and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector from the sending unit.
Remove the sending unit using a socket or wrench.
Install the new sending unit by tightening it to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Reconnect the electrical connector.

5. Check for Leaks and Reassemble

Start the engine and let it idle while checking for oil leaks around the oil filter and sending unit.
If no leaks are present, turn off the engine and reconnect the battery.
Clear any diagnostic trouble codes using an OBD-II scanner if necessary.
