hi, i have a mustang cobra, but it doesnt reads the mph, and it shows this code P0720 Output Shaft Speed Sensor circuit. i already put a new sensor from ford, thinking it was that, and its still the same thing, i checked if the tranny had the gear that makes the sensor measure the mph, and yes it has it, i dont know how to check if the cluster its fine, i disconnect the battery and connect it again and al the gauges move, so i dont know if thats the way to check it if it works, and i dont know how to check if the sensor its getting signal, maybe its a broken cable of the harnes, but i dont know how to check that? can some one help me please, cause i cant use the car like this and i want to go to houston on christmas in my car not in my dad's truck, so can some one help me out ill apreciated a lot, thanks
