Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Using a funnel, add the appropriate type of engine oil (5W-30 synthetic is recommended for the Civic).
Recheck the oil level with the dipstick and ensure it is within the safe range.
Replace the oil filler cap securely.

3. Replace Oil Filter

Using an oil filter wrench, remove the old oil filter.
Lubricate the rubber O-ring of the new oil filter with fresh oil.
Install the new oil filter, tightening it by hand until snug, then an additional ¾ turn.

4. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit on the engine block.
Disconnect the electrical connector and unscrew the sending unit using a socket wrench.
Install a new oil pressure sending unit, tightening it to manufacturer specifications (typically around 20-30 ft-lbs).
Reconnect the electrical connector.

5. Check for Leaks

Start the engine and allow it to idle.
Inspect the area around the oil filter and oil pressure sending unit for any signs of leaks.
Monitor the oil pressure warning light; it should turn off if the issue is resolved.
