Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the vehicle is on a level surface and securely supported with jack stands if needed.

2. Address Diagnostic Trouble Codes (DTCs)

If specific error codes were retrieved, research the codes to identify affected components.
For example, if the code indicates a faulty oxygen sensor, locate the sensor in the exhaust system.

3. Replace Faulty Components

Oxygen Sensor Replacement (if applicable)
- Tools Required: Oxygen sensor socket, ratchet, torque wrench
- Remove the old sensor using the oxygen sensor socket.
- Install the new sensor and torque to manufacturer specifications (typically around 30-35 ft-lbs).
Gas Cap Replacement (if applicable)
- Inspect the gas cap for cracks or wear, and replace if necessary.

4. Clear Error Codes

Reconnect the battery terminal.
Use the OBD-II scanner to clear the error codes after repairs are completed.

5. Final Checks

Start the engine and allow it to reach operating temperature.
Observe for any return of the check engine light.
