Abstract
Methods and systems are presented for improving operation of an evaporative emissions system. In one example, the methods and systems estimate a fuel vapor concentration based on output of a fuel tank level sensor and output of a fuel pressure sensor. A canister purge valve is adjusted to an initial position at a beginning of a fuel vapor purging cycle to reduce a fuel vapor purging time.
