That's the one I have on the 04... which I just cleaned. I'll report back if it fails.
It's a slide valve actuated by (? I think) a linear motor, about the same a solenoid except it responds more positively. It could just be a solenoid.... The black portion oscillates back and forth.
Other IATs I've seen (Volvo, earlier Taurus) have been rotary valves on little conventional (rotating) motors.
