Abstract
Methods and systems are provided for operating an engine to generate vacuum for a subsequent leak detection routine. During a selected key-off condition, a starter motor is operated to spin the engine unfueled and generate intake vacuum for the leak detection. Fuel vapors drawn during the spinning are stored in an auxiliary canister that is purged along with a main canister during purging conditions.
