Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical issues during inspection.

2. Check Oil Level and Quality

Tools Required: Dipstick
Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the oil level.
Assess the oil's color and consistency; it should be amber and smooth.

3. Inspect for Leaks

Tools Required: Oil catch pan, flashlight
Look for leaks under the vehicle, particularly around the oil filter and oil pan.
If leaks are found, tighten the oil filter and drain plug as necessary.

4. Scan for Error Codes

Tools Required: OBD-II scanner
Connect the scanner to the vehicle’s OBD-II port.
Record any trouble codes and address them as necessary.

5. Replace Air Filter (if needed)

Tools Required: Screwdriver (if applicable)
Open the air filter housing and inspect the air filter.
Replace with a new filter if it is dirty or damaged.
