Before you buy a new try rewiring it at the sensor. Salt ate up the wires on mine but the sensor was fine. I cut wires at the sensor, pulled out the wire terminals, cut the leads back until I had clean wire, used 3M bullet style terminals (blue)on the on the clean leads. (remove the blue plastic from the terminals) Slide the terminals into the sensor and check to see if it is functioning, if not reverse the terminals. When it is working, tape the heck out of it. Mine has made it through 2 detroit winters since this repair.
