Methods and systems are presented for diagnosing operation of a fuel tank pressure sensor. The methods and systems may include releasing fuel vapors from a fuel tank to an engine when an engine is rotating in a fuel cut out mode while a catalyst temperature is greater than a threshold temperature to determine whether or not the fuel tank pressure sensor is degraded.
