Ahhh... Joe..... the SM says the solenoid valve opens and closes a vacuum line to the IRIS. So it uses vacuum pressure stored in a reservoir that is controled by an electric solenoid.

OK, OK, ya got me John.

However, I was responding to Nick saying the butterfly valve was, and I quote, "actuated" by vacuum.

Over here, actuated implies control. So farther up the command chain, the ECU actuated the solenoid, which changed the voltage to open the valve to let in the vacuum to change the butterfly position to improve the charge velocity yadda yadda

It was a lot easier in the old days when our feet did most of the going and stopping, and our hands shuffled it in the general direction of "home"
