Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the oil filler cap and use a clean funnel to add oil if the level is low.
Use the correct oil type as specified in the owner’s manual (e.g., 5W-20).
Replace the oil filler cap securely.

3. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter).
Use a socket wrench to disconnect the electrical connector from the sending unit.
Unscrew the old sending unit using a wrench.
Apply thread sealant to the new sending unit's threads and install it.
Reconnect the electrical connector.

4. Replace Engine Oil and Filter (if necessary)

Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the oil drain plug and torque to manufacturer specifications.
Remove the old oil filter using an oil filter wrench and install a new one, lubricating the gasket with new oil.
Fill the engine with new oil through the oil filler cap.
