Its function is quite straightforward – it measures a vehicle’s angular velocity on its vertical axis. Simply stated, it measures how far your vehicle is tilting in a turn. Information from your yaw rate sensor is provided to the car’s computer, where it is used to determine if too much yaw is present. If too much yaw is perceived, the computer can automatically apply the right braking pressure to one or more wheels, or adjusting engine performance to correct the problem. This makes sure your vehicle continues travelling in the direction you point the steering wheel.
