Need this part, unsure of name!!! (some sort of vac sensor?)

[Guest]

Hey, when I had my vac lines tidied up the plastic bits on this were so brittle that they just snapped off without any force, i've rangi'd up something to keep it going atm but would really like to replace it with one that isn't broken.

If anyone has one lying around or knows where I can get one cheap then please let me know

It's the solenoid for the charcoal canister. You can just block it off.

i had the vac lines that go into it put together and it made my car idle higher?

werid i removed mine and ddint do that...

oh ok, it brought the idle up from around 800 to 1000

did you take the thing out, link the vac lines and just have the plug hanging there? When i tried it i left the sensor sitting there and had it plugged in still with the vac lines connected

Try a wrecker, like Strongs or Waiuku Car Spares.

It would. Block them both and it'll be fine.

vapour from the fuel tank builds up and is stored in the charcoal canister

under conditions determined by the ecu, contents of canister is fed into the intake manifold. (that solenoid is opened) as far as i understand this is only during open throttle.

at idle (closed throttle) plumbing the canister straight in (bypassing the solenoid as mentioned before) effectively feeds more air to the engine, hence the rise in idle. its a vacuum leak.

this system is probably beneficial in a small way but its mainly for emission control - otherwise the vapour just builds pressure in the tank and escapes via the pressure release valve built into the fuel cap.

older motors have no solenoid but the canister is plumed straight into the throttlebody, right between the width of the throttle butterfly valve where it sits at closed throttle. it is blocked off at closed throttle.

there are one way valves going into and exiting the canister.

well thats how i understand it lol

...

whould this be the reason why i can have a good amount of pressure in my fuel tank ever sense i blocked the line were it comes through the firewall
