Nissan Maxima VIAS/Power Valve Default Behavior

[2002 Maxima SE]

Anyone know how this is supposed to work? I've heard a few versions.

When the car is off, my VIAS/Power Valve is in the open position. I define open as the valve is sitting perpendicular to the ground => | allowing the cavity in which the VIAS resides to be open to both parts of the intake.

Now, at a certain RPM the valve is supposed to close (parallel to the ground) => -- causing only the top portion of in the intake to be receiving incoming air.

Should the VIAS be in -- or | at low RPM (below 3000)?

Last night, I put a string in the arm so that if it closed (--) it would drop the string. This morning, driving to work, I went up from 60 MPH to 75 MPH and reached 3100 RPM. The VIAS never moved though.

OK, found this on maxima.org (for anyone interested)

Quote:
On the 02-03, the VIAS has its default position as open, but is closed via vacuum and ECM control from 1800-3600 rpm, so when any part of that mechanism is faulty, the valve remains open throughout the RPM band.

Now just need to check which part is not allowing it to close (actuator, solenoid or vaccuum cannister).
