Solution

1. Preparation

Gather necessary tools and parts before starting.
Tools Required: OBD-II scanner, socket set, oil filter wrench, torque wrench, oil catch pan.
Safety Warnings: Ensure the engine is cool before starting work. Disconnect the battery to prevent electrical shorts.

2. Check and Correct Oil Level

Remove the engine oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil level is low, add the recommended oil type (typically 0W-20 for Honda Civics).
If the oil appears dirty or contaminated, consider performing a full oil change again.

3. Inspect Oil Filter Installation

Locate the oil filter and inspect for any signs of leaks or improper installation.
If the oil filter is loose, tighten it by hand until snug, but do not overtighten.
If the filter is damaged or incorrectly sized, replace it with the correct part.

4. Reconnect Electrical Components

Visually inspect the wiring harness and connectors to the ECU and associated sensors.
Clean any corroded connectors and ensure they are fully seated.
Reconnect any loose connectors, ensuring they click into place securely.

5. Clear Fault Codes

Reconnect the battery if it was disconnected.
Use the OBD-II scanner to clear any fault codes.
Start the engine and observe if the check engine light remains off.
