Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to reset the vehicle's computer.

2. Scan and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition without starting the engine.
Follow scanner instructions to retrieve error codes.
Document the codes for reference.

3. Address Identified Issues

Based on the retrieved codes, check and replace faulty components (e.g., oxygen sensors, spark plugs, etc.).
- For Oxygen Sensor Replacement:
  - Locate the sensor (typically in the exhaust system).
  - Use an oxygen sensor socket to remove the old sensor.
  - Install the new sensor and torque to the manufacturer's specification (usually around 30-50 lb-ft).
- For Spark Plug Replacement:
  - Remove ignition coil connectors.
  - Unscrew and replace the spark plugs using a spark plug socket, ensuring they are gapped correctly (refer to the owner’s manual for specifications).

4. Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any codes that were stored.
Turn the ignition on to ensure the check engine light goes off.

5. Test Drive

Start the vehicle and monitor the dashboard for the check engine light.
Conduct a test drive to ensure the issue is resolved and the light remains off.
