Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Retrieve and Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Read the error codes and note them down for reference.
Clear the codes and see if they return after a short test drive.

3. Inspect and Repair Faulty Components

Based on the error codes, identify specific components to inspect.
- For example: If a faulty oxygen sensor is indicated:
  - Locate the oxygen sensor in the exhaust system.
  - Disconnect the wiring harness and remove the sensor using a socket wrench.
  - Install a new oxygen sensor, ensuring it is tightened to the manufacturer’s specifications (typically around 30 lb-ft).

4. Reassemble and Reconnect

Reconnect the battery terminal.
Ensure all components and wiring harnesses are properly reconnected.
Close the hood securely.

5. Final Checks

Start the vehicle and monitor the dashboard for any warning lights.
Conduct a short test drive to ensure the issue is resolved.
