The function of the crank position sensor is to tell the ignition system what degree the engine crank is at so it knows when to fire off the coil. The knock sensor detects detonation in the cylinders that causes a "knock", when the ECU detects said signal, it backs off the timing in order to prevent engine damage by reducing cylinder temperature.
