What Does This Sensor Do/ Do I Need It?

[vetter2769]

Hey guys so this sensor is located in my r34 gtt on top of the engine, close to firewall, it looks similar to a boost sensor, except one end of this is connected to plenum, and other end is connected to hard line under throttle body then connected to charcoal canister thing.

before I ask if I need it, my tooooona told me it extracts air/moisture from the fuel system, this would be rather handy to have as I'm running e85, big injectors high flowed turbo etc etc 300kw blah blah

so keeping the fuel system free from moisture. air would be bonus.

However, if theres a good chance its f*kt anyway (being 15 years old) then I'll just remove it.

If its a cheap part to replace then I'll replace it.

so questions -

what does it do?

whats the correct name for this sensor?

was my toooona correct?

Where can I buy one?

are they cheap?

why can't I get girls to like me?

whats the meaning of life?

thanks

Its a vac solenoid the ecu will turn it on when required eg at idle to suck fuel vapours through from the tank. recommend replacing it
