Dana 10486220 is a Dana Spicer speed sensor for off-highway axle applications. A speed sensor reads the passing teeth of a toothed ring on a rotating part and gives the control unit a speed signal. When the sensor or its connection starts to fail, a warning lamp that stays on, or comes and goes, is a common sign that the speed signal is dropping out.
