The car's computer routinely tests it and pops a code if it is out of certain bounds. As I've found to be the case though, sometimes things manage to go out without causing the computer to catch it.
The sensor is basically just a magnet with electrical wires going to it. As certain teeth on a wheel on the crankshaft pass past the magnet, it creates a voltage, which the computer reads and associates with a crankshaft position.
If you've got a multimeter, you should be able to test for the required resistance, as well as checking voltage as you try turning the engine over.
