Question -- what should I see as a correct result. Air passage closed both ways, one way, which way, etc? You alluded to this...but what specifics?[/QUOTE]


I alluded ????

It is a valve ..it can not flow until it is ON...it is a Directional valve..so it flows in the DIRECTION of the ARROW when it is ON...the signalis pulsed so as to meter the flow. [@ 5-20 htz, depending on ECU mapping]

Thats the specifics.
