Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil filter wrench, torque wrench, rags for cleanup
Allow the engine to cool down before starting any work.
Disconnect the battery negative terminal to prevent any electrical issues.

2. Address Error Codes

Connect the OBD-II scanner and retrieve any diagnostic trouble codes (DTCs).
Document the codes and clear them from the system to see if they return after a test drive.

3. Inspect and Correct Oil Change Elements

a. Check Oil Level

Use the dipstick to check the oil level.
If low, add the correct oil type as specified in your owner’s manual.

b. Inspect Oil Filter

Remove the oil filter using an oil filter wrench.
Check the rubber O-ring for any damage or debris; replace if necessary.
Install a new oil filter, ensuring it is tightened properly but not over-torqued.

c. Tighten Drain Plug

Inspect the oil drain plug for any leaks.
Tighten the drain plug to the manufacturer’s torque specifications (typically around 20-25 ft-lbs for most Honda models).

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and let it idle, monitoring for leaks or unusual noises.
Take the vehicle for a short test drive to ensure the check engine light does not return.
