This code means there's a problem with the car's sensor that helps detect if the car is about to tip over.
The roll over sensor is designed to detect if the vehicle is tilting or rolling over. It sends signals to the airbag control module to deploy the airbags in the event of a rollover.
The B0099 code indicates a malfunction in the roll over sensor circuit. This sensor is part of the vehicle's safety system and is responsible for detecting lateral acceleration and tilt, which could indicate a potential rollover situation.
