I believe it was this piece that broke off. The right side of the cross beam pretty much sheared off.

OK there it is, looks like the plastic piece at far left side of the pic. Also looks like the sensor has junkyard markings on it like the part has been replaced before. The sensor bolts to the steel crossmember so either that huge bolt fell out or part of the sensor broke off.
