Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

2. Address Error Codes

Using the OBD-II scanner, clear the error codes after noting them down.
If codes reappear after clearing, proceed with repairs related to those codes.

3. Inspect and Replace Components

Gas Cap:
- Inspect the gas cap for cracks or wear.
- Replace with a new gas cap if damaged.
Spark Plugs:
- Remove the ignition coil using a socket set.
- Inspect the spark plugs for wear; replace if necessary with OEM parts.
- Torque new spark plugs to the manufacturer's specifications (typically around 15-20 lb-ft).
Mass Air Flow Sensor (if applicable):
- Disconnect the electrical connector and remove the MAF sensor.
- Clean using MAF cleaner spray and reinstall.

4. Check and Repair Wiring

Use a multimeter to test wiring continuity for any sensors related to the error codes.
Repair or replace damaged wiring and connectors as necessary.

5. Reassemble and Test

Reconnect the battery and all components.
Start the engine and monitor for any abnormal sounds or lights.
