Canister Vent Valve: Description and Operation
Evaporative Canister Vent Valve
Description
The Evaporative Canister Vent Valve replaces the fresh air vent used on the past Evaporative Emissions (EVAP) canisters. The vent valve now
not only allows the fresh outside air to the EVAP canister during the purge modes. but also allows the diagnostic to pull a vacuum on the fuel tank
by closing the vent valve. This valve is normally open.
