Canister Vent Solenoid
WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
During the Evaporative Emission Running Loss System Test Monitor, Evaporative Emissions Repair Verification Drive Cycle and the Evaporative Emission System Leak Test the canister vent solenoid is closed to allow a vacuum to be drawn on the vapor management system. The canister vent solenoid is normally open.
