Question about 1999 Ford Taurus
Not knowing what kind of car.I would say check output speed sensor.You can do this simply.Find where it is located,it will be a socket.Unplug connection,get a multimeter,switch it to AC voltage.Connect one lead to a pin coming from switch , the other lead to the next pin.Now have someone put car in gear with drive wheeels off ground.If meter flucuates then Output speed sensor is good.Time to check wiring and continuity to instrument cluster.A cheat method is to have a scan tool that gives you live data.You plug in scan tool drive car and see if you get MPH.
