Solution

1. Preparation

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

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Record any error codes and their definitions for further analysis.

3. Inspect Components

Gas Cap:
- Remove and inspect for cracks or wear.
- Clean the sealing surface and ensure it clicks securely when reattached.
Spark Plugs:
- Remove spark plugs using a socket wrench.
- Inspect for carbon buildup or wear; replace if necessary.
- Torque new plugs to the manufacturer’s specifications (typically 13-16 lb-ft).

4. Check for Leaks

Inspect all vacuum and intake hoses:
- Look for cracks, loose connections, or signs of wear.
- Replace any damaged hoses with OEM parts.

5. Battery Inspection

Test the battery with a multimeter; it should read 12.6V or higher when fully charged.
Clean battery terminals and connections to ensure good contact.

6. Reset the Check Engine Light

After repairs, reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and monitor for any reoccurrences of the check engine light.
