At its core, check engine code B0025 indicates an issue with the vehicle’s Right Front Side Impact Sensor. This sensor plays a critical role in the vehicle’s safety system, as it helps detect impacts on the right front side of the car. When the sensor detects an impact, it sends signals to the airbag control module, which then deploys the airbags to protect passengers in the event of a collision. Therefore, any malfunction or error in this sensor’s functionality can compromise the effectiveness of the vehicle’s safety measures.
