Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Refill Oil

Check Oil Level
- Remove the dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the oil level.
- If low, add the correct type of oil (5W-20 recommended for Honda Civic).
Tools Required: Oil funnel, correct engine oil.

3. Inspect and Replace Oil Filter (if necessary)

Remove Oil Filter
- Use an oil filter wrench to remove the oil filter.
- Ensure the old filter’s rubber O-ring is removed with it.
Install New Oil Filter
- Lubricate the rubber O-ring of the new oil filter with a little new oil.
- Install the new oil filter by hand until snug, then tighten it according to the manufacturer’s specifications (typically 3/4 to 1 full turn after the O-ring makes contact).
Tools Required: Oil filter wrench.

4. Check and Replace Oil Pressure Sending Unit

Locate the Sending Unit
- Find the oil pressure sending unit, usually located near the oil filter.
Remove and Replace Unit
- Disconnect the electrical connector.
- Use a socket to unscrew the old sending unit.
- Install the new sending unit and reconnect the electrical connector.
Tools Required: Socket set, wrench.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to run for a few minutes, checking for leaks around the oil filter and sending unit.
