hi guy's,  

can anyone explain how the vapour fuel valve works on a 2002 1.4 MPi 8v.

 

i'm trying to trace a vacuum leak.

 

A hose from the throttle body goes to the vapour valve.

 

When i remove the hose from the valve and suck on the pipe, I can get a continuous draw.

 

Is this correct? Or is the valve passing?

 

cheers

the valve is buggered mate , with no power to it, there should be no air passing thru, then it is pulsed to meter the fuel vapor thru when needed.

Hi Felicia16v,

 

That's great info. I may have just found my vacuum fault. Gonna source a new valve.

 

Thanks again, you have just made my night shift!!!

 

Cheers
