A vapor canister having an integrated evaporative emission canister purge actuation monitoring system. The vapor canister has a plurality of sidewalls defining a housing with a valve body formed integrally on the housing and a cover mounted to the valve body so as to define a vent chamber between the cover and the valve body. The integrated valve body has a main flow passage and a canister port. An air filter assembly is disposed adjacent to the valve body on the housing and provides fluid communication between the main flow passage and the ambient air. A first one-way umbrella valve mounted to the valve body that is responsive to predetermined positive pressure in the main flow passage to control flow of fluid from a vapor canister to ambient air as well as a second one-way umbrella valve that is responsive to a predetermined negative pressure in the main flow passage to control the flow of ambient air through an air filter assembly.

An evaporative emission canister purge actuation monitoring system includes an integrated valve body having a main flow passage, a first one-way umbrella valve mounted to the valve body that is responsive to predetermined positive pressure in the main flow passage to control flow of fluid from a vapor canister to ambient air as well as a second one-way umbrella valve that is responsive to a predetermined negative pressure in the main flow passage to control the flow of ambient air through a fresh air port. A vacuum actuated switch is supported by the integrated valve body and in electrical communication with a control unit. The switch is responsive to negative pressure in the main flow passage to send a signal indicative of the predetermined negative pressure to the control unit.
