Abstract
Methods and systems are provided for operating an evaporative emissions system in a turbocharged engine. In one example, a method may include pulsing open a canister purge valve responsive to the turbocharged engine entering a boosted mode of operation. The canister purge valve may be opened for a duration long enough to close a check valve coupled between the canister purge valve and an intake of the engine.
