    Found this with Google; http://www.google.com/search?q=safte...w=1024&bih=664

    "Evaporative Emission (EVAP) System Flow During Non-Purge"

    If the Evap purge valve does not seal properly, fuel vapors could enter the engine at an undesired timing causing drivability concerns. The control module tests for this by commanding the EVAP purge valve OFF closed and vent valve ON closed, sealing the system, and monitoring the FTP for an increase in vacuum. If the control module detects that Evap system vacuum increases above a calibrated value, DTC P0496 will be set.

    If I remember correctly it was a very easy fix and cheap as well ($20 or so).
