You probably got a P0496. The Purge Control Solenoid Valve (PCSV) is mounted behind the throttle body. The usual testing method is to use the Kia scan tool to actuate it and check for clicking or applying 5 volts and checking the plunger for movement. Be careful, it is difficult to remove and you'll probably split the hose before you get it loose from the PCSV.ok im getting the =evap high purge flow valve code. where do i start on this, where is the valve and is there a way to test it.
