    摘要: An apparatus and method for use in diagnosing an evaporative emission canister collection and purge system. An EVAP system of a vehicle is diagnosed through the use of a mechanism wherein a change in conductivity occurs in response to a change in concentration of fuel vapor in the variably conductive mechanism. By sensing the change in conductivity, a diagnostic mechanism determines whether the vapor collection and purge systems are operating correctly.
