Principles of Operation
Evaporative Emission (EVAP) Check Valve
The check valve vent is normally closed. When the EVAP system enters a purge cycle, the valve forces the purge air, being drawn in, to enter the system
through the remote canister vent tube. During refueling the valve vent opens allowing the displaced air to vent freely to the atmosphere through a more
direct and lower resistance path.
