Yaw sensor

The vehicle should not drive any different. The ABS light is most likely on. The yaw sensor only senses the angular velocity so that the ABS system can active if needed. All it does is tell the ABS what this angle is and then the ABS reacts. It is not going to cause the vehicle to drive differently. At worst the ABS will activate when it should not.

Let me know if I miss understood what you were asking. Thanks
