Dtc Code P0496

[sjsulek]

I have a 2005 Denali XL with the 6.0L V8. Engine light is on and it's throwing the P0496 code. I read to first replace the Vapor Canister Vent Solenoid, GM Part 25932571. I did that and the CEL stayed off for 36 hours, now it's back on. Is my next step the Vapor Canister Purge Solenoid, GM Part 12581282? If that's my next move, where is it located in the engine compartment?

THANKS FOR ANY HELP!

I have the same truck but my code is PO449 which the dealer told me it is the EVAP vent solenoid. I will try to replace it if I can find it. Can you shed some light on this to help me? Thanks
