Abstract: A system according to the principles of the present disclosure includes a valve lift determination module and a fault detection module. The valve lift determination module determines valve lift based on at least one of a first period when a valve is open and N differences between a first value of a valve lift signal generated by a valve lift sensor when the valve is closed and a second value of the valve lift signal when the valve is open, wherein N is an integer greater than one. The fault detection module detects a fault in a valve actuator based on the valve lift.
