If the code is set, that only means the problem is in that circuit. The way it died when you slammed the passenger door would suggest that it may be in a wire that's attached to the body. The engine mounts would probably dampen the shock enough so that it wouldn't affect the crank sensor itself or wires on the engine. Or maybe not, or maybe it just died on it's own at the time you slammed the door, it's hard to say. I would suggest just replacing the crank sensor and see if that fixes the problem, of course that is assuming that they checked for obvious problems with the wires when you took it in.
