What Does P0496 Code Mean?

OBD-II Code P0496 is defined as a Evaporative Emission System High Purge Flow

The evaporative control (EVAP) system captures any fuel vapors from the fuel tank and sends them through the vehicle's intake to be burned in the normal combustion process. The EVAP Purge Valve allows vapors from the EVAP System to enter the intake and go through the engine's combustion process. When the engine control module (PCM) detects the evap system is purging when it should not, it will set code P0496.
