Yes you can fix this your self, that code is usualy for the Evaporative Emissions (EVAP) Canister Vent Solenoid/Valve wich is under the suv in the back. .



Broken wires near the canister vent solenoid are a common problem

Remove the spare tire and you will see the valve. I had this happen to my 07 Tahoe, easy fix I got the valve at the dealer for under $50

I got the P0496 Code last week and It was the purge valve and the canister, So the p0449 is something else beside those two. Also the parts department told me that the canister never goes bad and GM had made a poor design choice so there is a replacement for this. I went to autozone and they told me its either the purge valve or canister I just replaced both just in case. I think the canister caused the purge valve to mess up.
