Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Oil Level and Type

Reconnect the battery terminal.
Use the dipstick to check the oil level; add oil if low.
Ensure the oil type matches manufacturer specifications (typically 0W-20 for Honda Civic).

3. Inspect and Replace Oil Filter

Remove the oil filter using an oil filter wrench.
Inspect the old filter for any signs of damage.
Apply a thin layer of clean oil to the rubber gasket of the new filter.
Install the new oil filter by hand, tightening it according to the manufacturer’s specifications (usually hand-tight plus a quarter turn).

4. Verify Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually found near the oil filter.
Disconnect the electrical connector and inspect for damage.
Use a multimeter to test the unit’s resistance; replace if faulty.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored error codes after addressing the issues.
Start the engine and check if the check engine light remains off.
