The cam sensor is used to position sequential fuel injection. I am pretty sure that is all that happens if you disconnect it is the injectors are group fired instead of sequentially fired. This is the way it works for many engines. I'm not sure about all. Try disconnecting it while running. That is if you can clear the code it will cause. I doubt the car will do much more than a small one time shudder.
