Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues during inspection.
Allow the engine to cool down before working.

2. Inspect and Correct Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and pull it out to check the oil level.
- If the oil level is low, add the recommended oil type to the appropriate level.
- If the oil level is high, drain excess oil to avoid damage.

3. Replace Oil Filter

Locate the oil filter using a wrench.
Remove the old oil filter, ensuring to catch any residual oil in a pan.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, tightening it to the manufacturer's specification (typically hand-tight plus 3/4 turn).

4. Inspect Wiring and Connectors

Visually inspect all wiring and connectors around the oil filter and engine area.
Reconnect any loose connectors and repair any damaged wiring.

5. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and observe if the check engine light remains off.
