Reason:
Sensors fail temporarily because of ice or water

I had the same issue. Turn the engine off, handbrake on and select reverse, get down and listen to each sensor, and you should hear a clicking. Make sure every sensor is clicking. If not, then check connection at the back of the sensor (you have to remove the bumpers!) and also check the loom for any damage.
