I can't seem to find anything usefull on the net either... but the problem is in the EVAP system, with the purge control valve circuit.. so what i need to know is..

where is the purge control valve?.. It could be a problem with a loose connecton as it is stated as a circuit malfunction.

It could also be that the seal has gone on the fuel cap (will listen for the hiss next time i take it off) or one of the vacuum hoses needs cleaned out... anyone able to shed a little more light.. please?
