2.0 Turbo Carbon Filter Sensor

[Ant 2]

My 2.0 turbo is running spot on, but after 3 years im actually wondering if the carbon filter valve / sensor that is attached to the inlet throttle is actually needed ?

 

There is an electrical connection to the valve, so i'm wondering if this effects the ECU in anyway.. At the moment it just plugs into the inlet and the other side of the valve is just left open.

 

How have other people done this ?

 

Cheers

you mean solenoid not sensor? pretty common across the range so doesnt have to come off a turbo.

 

It doesn't affect the engines running in any way as long as the pipe is blocked off if you remove it, that's as long as your car doesn't run a charcoal canister, if it does you do need it there but they are fairly rare on a 205.

 

it will throw up a fault code if disconnected but won't bring the Engine management light on.

Sorry to hijack, but where are you saying to block off - after the solenoid or after the throttle body - I need to do this on my gti6

After the throttle body if you are removing the solenoid, which you may aswell if you arent running a charcoal cannister!

Thanks, I think I have worked out how it works, correct me if I'm wrong. The fuel vapours go from the tank to the cannister - then the solenoid thing lets them through to the throttle body - then mixed with the air in the inlet mani. So it makes sense to block off at the throttle body, otherwise I guess I'd have a vacuum leak.

 

Any tips on what to use to block it off with?!

yep you've got it, anything that fits in the hole

what's the actual point of releasing tank vapours into the inlet manifold?

 

i take it the carbon canister is used to "filter" the vapours so that the resultant air is clean , but then why not just release it to atmosphere? or is it the case that it will still contain some fuel vapour and so it's best if it's burnt?

yup, its all emissions doodahs just like catalytic converters and exhaust gas recirculation systems.
