Default What is an EVAP emission 2 way valve?

On Preludes, this sensor is hooked up to one of the nipples coming off from the EVAP cannister.

I need to know what exactly this is so I can figure out the vacuum wiring to put it into my civic.

Can anybody take a pic of it? It's nothing on the engine...it's the one nipple that doesn't go to the engine from the cannister.

I need to know if it's just a valve, or if it's an actual sensor that needs wiring to go with it.

If it's a valve....that'd be great! I can just hook it inline!

But if it's got wiring...I've got no clue what I'll do about it.

Anyway, any help will be greatly appreciated. TIA Click the image to open in full size.

C'mon!

Somebody HAS to know this.

At least scan me some pics of the manual and let me figure it out!

I've got scans of most of the actual vacuum system...but it doesn't continue over to the EVAP Two Way Valve...

Because the evaporated fuel goes both ways. the fumes that evaporated into your charcoal canister are sucked back into the tank for combustion when you drive the car.

There is a sensor that determines that the purge is taking place, or else you throw a code.
