Abstract: A method of operating an internal combustion engine that includes a valvetrain having a rocker arm assembly including a rocker arm on which a latch pin is mounted. An actuator for the latch pin, including an electromagnet, is mounted separately from the rocker arm. Rocker arm position information is obtained by gathering and analyzing data relating to a current or voltage in an electrical circuit that is operative to power the electromagnet. The rocker arm position information is used to perform a diagnostic.

Abstract: An actuator comprises a hollow first piston (11) comprising a first extant with a first outer diameter (D1) and a second extant comprising a second outer diameter (D2), where D1>D2. A second piston (12) is slidable within the first piston. An actuator housing (14) comprising a recess (22), a first tubular port (23) in communication with the first piston, and a second tubular port (24) in communication with the second piston. The first extant has a length (L1) and wherein the second extant has a length (L2). The first tubular port extends for a length (L4), and the recess extends for a length (L3), where L4≧L2, and where L3>L2>L1. The first piston and the second piston are housed in the recess.
