Perhaps you are referring to vehicle speed sensor. A wheel speed sensor or vehicle speed sensor (VSS) is a type of tachometer. It is a sender device used for reading the speed of a vehicle's wheel rotation. It usually consists of a toothed ring and pickup and usually mounted on top of the differential. The VSS input reading sent to PCM for shifting the gears properly.
