The sensor is fitted behind the front bumper to the right of the radiator.Best thing to do is buy a car repair manual for this model mondeo,most car accessory shops will have one,it shows you exactly what you need to do.Although its unlikely to be a faulty sensor,more likely to be the wiring to it,its on a connector,so it might have been disconnected.Hope this helps....Gordon
