The gears get worn, causing the electronics to hunt the play between the teeth, so that causes the electronics to work constantly to maintain throttle position. So the gears get 'rattled' to death and the electronics fry themselves in the process. So when the teeth are shot and you get the error code, the electronics have also had time to cook.
