Abstract: An active canister purge system may include: a canister trapping a fuel vapor generated in a fuel tank; a purge control valve allowing the trapped fuel vapor to be purged from the canister into an intake pipe; a purge pump forcefully pumping the fuel vapor trapped in the canister into the intake pipe; a pressure sensor detecting a pressure at an inlet of the purge control valve; and a controller determining whether the pressure at the inlet of the purge control valve is varied on the basis of a pressure variation in the intake pipe in a non-purging condition to diagnose an open stuck state of the purge control valve.

Abstract: A method for diagnosing a purge valve of a canister purge system includes (a) determining whether a purge valve, which is installed on a purge pipe connecting a canister with an intake system of an engine, is open and whether a purge pump is running, wherein the purge pump is configured to pump evaporative emission captured in the canister toward the intake system, and (b) determining whether the purge valve is in a close stuck state, based on upstream pressure and downstream pressure of the purge pump, when the purge valve is open while the purge pump is running.
