1985 Ford F-150 - Coolant Overflow Tank And Reservoir

Ford F-Series Coolant Recovery Tank

Your Ford F-Series' vehicle speed sensor sensor sends data to the electronic control unit about the speed of the crankshaft. Combined with data from other sensors, the computer will use this information for a variety of systems, including cruise control, transmission shifting, and the speedometer reading. Over time, your Ford truck's vehicle speed sensor can send erratic signals, or may stop working altogether. If your Ford F-Series truck has an erratic or inoperative speedometer, poor shifting, or if the cruise control won't work, the vehicle speed sensor may have failed. Hard shifting can also cause transmission damage with time, so replacing the vehicle speed sensor may help extend the life of the transmission. O'Reilly Auto Parts carries vehicle speed sensors for your Ford F-Series so you can make a full repair and you can get your truck back to work.
