mweston63 Posted December 23, 2009 Report Share Posted December 23, 2009 Have a 06 CTS with the 3.6L. Check engine light came on, and as P0496 (EVAP system flow during non purge). I replaced the purge valve on the intake, and inspected the hose to the intake from the valve. I blew it out, and it had very little carbon/trash in it. The code and check engine light is still active. Does it have to cycle to clear the fault? Am i missing something? Do I have to clean another sensor or clean the intake? I filled the tank and drove around for 30 min, and it's still on. I am going to wait a few days, unless someone has a better suggestion.
