Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, oil filter wrench, new oil filter, engine oil (correct type and viscosity).
Ensure the engine is cool to prevent burns.

2. Check Oil Level and Type

Remove the dipstick and wipe it clean.
Insert the dipstick back and remove it to check the oil level. Add oil if necessary.
Confirm the oil type used matches the manufacturer’s specifications (typically 0W-20 for this model).

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the oil filter.
Inspect the old oil filter’s rubber O-ring for damage or remnants stuck on the engine.
Apply a thin layer of new oil to the rubber O-ring of the new oil filter.
Install the new oil filter by hand until snug; do not overtighten.

4. Clear Any Error Codes

Use the OBD-II scanner to check for any error codes that may indicate specific issues.
If codes are present, follow the manufacturer’s guidelines to address them.

5. Recheck Engine Components

Inspect the air intake system for any loose connections or dislodged components.
Ensure all vacuum lines are connected and free of cracks or leaks.
