Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Use a funnel to add the appropriate type and amount of oil if the level is low (refer to owner's manual for specifications).
Replace the oil filler cap and reconnect the battery terminal.

3. Replace 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 socket wrench to unscrew and remove the old sending unit.
Apply thread sealant to the new sending unit and install it securely, tightening to the manufacturer's specified torque (consult service manual for specifics).
Reconnect the electrical connector.

4. Replace Oil Filter (if necessary)

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, hand-tightening it until secure.
Make sure to follow any specific installation instructions provided with the filter.

5. Fill and Check Engine Oil

Add the correct type and amount of oil to the engine.
Start the engine and let it idle for a few minutes.
Check for any oil leaks around the sending unit and oil filter.
Turn off the engine and wait a few minutes, then check the oil level using the dipstick again.
