Getting Code reading Po 440 - Evap. Emission System
Freeze Frame in my reader says "Fuel Syst 1 CL Fault"

Can anyone shed light on this as to what may be causing this code ? Thanks.

Also,, while checking out vacuum lines to Turbo found the "Boost Controller/sensor" that is supposed to be hanging off the air filter box just sitting in there not attached to anything. It appears there are 2 bolts that affix it to the air box.
Does anyone know length / diameter of these bolts?

Oh, and one last thing... right in this area there is a plate affixed to the engine that has the characters
"95EW95749" stamped on it. Anyone know what this is? ... I bought this car as a "96 not a "95 ... any ideas?
It is a "Canadian" version.

Love the car... getting it closer to optimum now weather is finally cooperating.

Thanks.

    The p0440 is a leak in the EVAP system. Either the gas cap wasn't tight enough, the purge valve died, or there is a hose leak somewhere between the gas tank and the charcoal canister.

    No clue regarding the 2 torx screws.

    The '95' could be year of manufacture and not model year.

      Ok... thanks Klaus... I'll check hoses first... then cap. Is the purge valve easily accessible?... not much is... it seems.

      Appreciate your input.
