Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts during inspection.

2. Scan and Interpret Fault Codes

Use an OBD-II scanner to connect to the vehicle's diagnostic port.
Record any stored fault codes and interpret them according to the manufacturer’s service manual.
Clear the codes and see if they return after a short test drive.

3. Address Identified Issues

Based on the fault codes:
- If a sensor is faulty (e.g., oxygen sensor, mass airflow sensor), proceed to replace the affected sensor.
  - Remove the electrical connector and any clamps or brackets securing the sensor.
  - Install the new sensor and reconnect the electrical connector.
- If there’s a fluid leak (e.g., oil, coolant), identify the source and replace gaskets or hoses as necessary.

4. Reconnect Battery and Test

Reconnect the battery terminals, ensuring a secure connection.
Start the vehicle and observe the dashboard for any warning lights.
Test drive the vehicle to ensure that performance issues are resolved and no new lights appear.
