Answer 1

P0496 Evaporative emission (EVAP) system flow during non purge

What detects this code P0496 is the FTP (fuel tank pressure ) sensor. To verify that the purge is open it will show on the fuel trim as a lean condition, on one side of the Bank  but not necessarily set a lean code, The purge should be replaced, this is a common code condition with the purge solenoid.
