Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, and clean rags.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the engine light.
Clear the codes and see if the light returns after starting the engine.

3. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully, then pull it out to check the oil level.
If the oil is low, add the appropriate oil type and viscosity. If the oil appears dirty or contaminated, consider an additional oil change.

4. Inspect Oil Filter Installation

Use the oil filter wrench to remove the oil filter.
Inspect the old oil filter's rubber O-ring; if it’s stuck to the engine block, remove it.
Install a new oil filter, ensuring it is properly seated and tightened to manufacturer specifications (typically hand-tight plus a quarter turn).

5. Check for Leaks

Start the engine and visually inspect for oil leaks from the oil filter and oil pan.
If leaks are present, tighten the oil filter or oil pan bolts as necessary.
