In some embodiments, an apparatus includes a solenoid and a solenoid controller. The solenoid is configured to move an actuator a distance between a first position and a second position when a voltage is supplied to the solenoid. The solenoid controller is implemented in at least one of a memory or a processor, and includes a feedback module and an output module. The feedback module is configured to receive a feedback signal associated with a solenoid current after the voltage is removed from the solenoid. The feedback module is further configured to determine whether the distance is less than a maximum distance between the first position and the second position (i.e., a “stroke”). The output module configured to produce an output signal when the feedback module determines that the distance is less than the maximum distance.
