A canister purge valve is a solenoid valve controlled by the Power Train Control Module. The Power Train Control Module is a control unit that determines the ignition timing, fuel amounts and other parameters needed to keep the engine running.
One side of the vent valve is connected to the charcoal canister. Another side is connected to the vent hose that has a filter or screen at the end and is attached to the car body or frame. In some cars, the vent valve is attached to the canister. In others, it's installed separately near the canister. The vent valve is controlled by the engine computer (PCM). Normally the vent valve is open. It closes when the engine computer tests the EVAP system for leaks.
