Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid electrical shorts.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Address Diagnostic Codes

Sub-step 1: Using the OBD-II scanner, retrieve the error codes.
Sub-step 2: Research the codes to identify specific components or systems needing repair.
Sub-step 3: Clear the codes and perform a test drive to see if the light reappears.

3. Repair or Replace Faulty Components

Sub-step 1: If a faulty gas cap is identified, replace it with a new OEM cap.
Sub-step 2: For faulty spark plugs, remove the ignition coils and replace the plugs with new ones, torquing them to the manufacturer’s specifications (typically around 13 lb-ft).
Sub-step 3: If ignition coils are faulty, disconnect the wiring harness and remove the bolts securing the coils. Replace with new coils.

4. Inspect and Clean System Components

Sub-step 1: Inspect the air intake system for cracks or loose connections and replace any damaged hoses.
Sub-step 2: Clean the throttle body using a throttle body cleaner to ensure proper airflow.
Sub-step 3: Check the fuel filter and replace it if clogged, ensuring to relieve fuel system pressure beforehand.

5. Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and monitor for any abnormal sounds or behaviors.
Sub-step 3: Perform another scan for error codes to ensure no new codes have appeared.
