Imho they should call it something else because it's confusing to many people who think the VSS is to blame for speedometer issues when in fact these are usually caused by ABS sensors, which are the actual speed sensors. VSS does not "sense" the speed, it just reads it from the ABS sensors. If I understand correctly what it senses is transmission speed.
