Knock sensor is a high tech mic attached to the engine block and the moment it senses ping, it retards the timing. If high octance is specified then using regular fuel will lead to knock. OTOH if a engine specified for regular fuel knocks or knocks with high octane there are other issues to be looked into from timing to excessive carbon build up.
