I was at a track day on Friday, and during the first run group the brake pad wear warning message came on ('07 CS). I brought the car in, and noticed that my left front pads had very little material left (the right front was in better shape--this track is very hard on the left sided tires, so likely brakes as well). In any case, I parked the car (I didn't have extra pads). When I started it to drive it home, the message had cleared (these are the stock original pads). I thought these sensors, once the circuit was broken, were broken.

Any thoughts? I was wondering if the sensor got hot enough to increase the resistance enough to make the computer think it was worn through?
