Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and document any trouble codes that appear.
Cross-reference the codes with a repair database to identify possible issues.

3. Address Identified Issues

Based on the retrieved codes, follow specific repair procedures:
- If the code indicates a faulty sensor (e.g., O2 sensor), disconnect the battery, replace the sensor, and reconnect.
- If the code relates to a misfire, inspect spark plugs and ignition coils for wear and replace as necessary.
- For fuel system issues, check for clogged fuel filters or malfunctioning fuel injectors, replacing components as needed.

4. Reset the Engine Control Module (ECM)

After repairs, use the OBD-II scanner to clear the trouble codes from the ECM.
Turn off the ignition and disconnect the scanner.

5. Test Drive

Start the engine and allow it to reach operating temperature.
Take the vehicle for a test drive to monitor performance and ensure the service engine light does not reappear.
