The vehicle speed sensor on trans axle on the passengers side. Here is a diagram to help you see where it is. Check the fuses first.

I'd check the vss, my info says top rear of transaxle, probably two wire connector, wire colors purple and yellow. Some makes and models, I can find it by removing the passenger side tire. Not sure about your model, my database wasn't exact about the location.
