Default Evap canister - where?

Hi All,

Where is the EVAP canister on a '99 9-3 2.0 S Convertible? I have looked by the headlights and near the fuel tank but I can't find it! Traced the hose back from the EVAP valve through the firewall/bulkhead but it seems to just run along the bottom to near the fuel filter to the petrol filler tube?

Sorry for asking but any ideas?

Thanks,
Si.

In the US, it's in the right side (from steering wheel perspective) front fender... Ron

Thanks - so follow hose from EVAP valve through firewall and then somewhere there near road wheel (on passenger side in US/but drivers side in UK)? I guess there is protective cover between it and road wheel?

Yes - it's behind the plastic wheel well liner.

Many thanks.

Do you agree that a choked canister could give me weird stalling issues?

Unlikely - more probable that a large leak would cause problems.

Plug the throttle body where the evap vacuum line enters and see if that helps.

Note: this might throw a CEL.

Thanks - so take off the TB vacuum line from the EVAP valve and plug (with paper or something?) the whole on the TB or the vacuum pipe?

Will I need the CEL resetting or will it go out on its own later?

Thanks again

Remove the line from the throttle body itself and secure a rubber cap over the inlet.

If this throws a CEL it will clear on its own, but that may take some time (a few drive cycles). You can also reset the CEL by disconnecting the battery for a few minutes (though on my '96 it only takes a few seconds).

Ok. Couldn't find a rubber cap so used my finger. Idles a lot lower but I think nicer. No stall so far but bonnet/hood was up. Really need to cap it with something with hood down to test properly.

Ok. Capped it off (securely I hope) and bonnet/hood down. Stalled again. I guess that rules out EVAP canister and EVAP valve?

EVAP valve appears to be quickly ish (regular) clicking when engine running. Does this sound right?

Thanks.

Evap is _probably_ not the cause, but it's certainly possible that there is more than one leak.

Clicking noise is normal.
