okay i had a quick look thru service manuals and searched here a bit but can't find the answer.

so on the front head of a 1.6a efi motor, are 2 presure switchs (well i think they are) one leads to a diaphram on the back of the motor, and the other leads to the charcol canister. can someone, advise one what are they , what they do , and replacement price. and what the diaphram on the back does?

I think they are part of the polution control but not sure.
