Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and basic hand tools.
Park the vehicle on a level surface and ensure the engine is off and cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Reconnect the OBD-II scanner to the vehicle and record any error codes.
Research the codes to determine the specific issue and required repairs.

3. Inspect and Replace Components

Gas Cap:
- Check for cracks or a poor seal.
- Replace if necessary (use OEM or compatible).
Air Filter:
- Remove the air filter housing cover.
- Inspect the air filter; replace if dirty or clogged.
Battery Check:
- Use a multimeter to check battery voltage; it should read between 12.4V to 12.7V when the vehicle is off.
- Clean any corrosion from the terminals and ensure tight connections.

4. Oil and Fluid Check

Remove the dipstick and check oil level and condition.
If oil is low or dirty, perform an oil change using the manufacturer-recommended oil type.

5. Exhaust System Inspection

Visually inspect the exhaust system for any signs of damage, rust, or leaks.
Repair or replace components as needed.

6. Reconnect Battery

Reconnect the negative battery terminal.
Clear any error codes using the OBD-II scanner.
