Abstract
A method of noise filtering a sliding camshaft actuator pin position output signal includes determining an actual pin position output signal period of a sliding camshaft actuator that occurs within a predetermined output signal period measurement window and establishing a pin position output signal filter window based on the actual pin position output signal period. Thereafter, the actual pin position output signal period from the sliding camshaft actuator is monitored by a control module and signals that occur outside of the pin position output signal filter window are rejected accordingly to prevent responding to false triggers.
