Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery negative terminal to reset the system and prevent electrical issues.

2. Addressing Error Codes

Reconnect the OBD-II scanner to the vehicle and document any codes.
Research the codes to determine the corresponding issues with the vehicle.
If a code pertains to a specific sensor (e.g., oxygen sensor), prepare to replace that component.

3. Replace Faulty Components

For example, replacing an oxygen sensor:
- Locate the oxygen sensor using the vehicle's service manual.
- Disconnect the electrical connector and unscrew the sensor using a socket wrench.
- Install the new sensor, ensuring proper torque (typically around 30 Nm) and reconnect the electrical connector.

4. Reset the Check Engine Light

Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Close the hood securely.

5. Final Inspection

Start the engine and allow it to reach operating temperature.
Check for any new error codes and monitor engine performance for abnormalities.
