I believe that when these sensors of fail they default two hot. In other words when the center becomes disconnected the gates sees that it's disconnected and then defaults to full hot. Because of the false the full hot it tells you that the sensor is not working or the wire is disconnected. So I would check in the engine compartment and make sure that the wire to the sensor is properly connected. If it is connected then the problem is a faulty sensor most likely.
