P0449 code

[bangon]

Hello gentlemen. My 2007 yukon denali is throwing out a evap code P0449. I'm told the first place to check would be the fuses. Can anyone point me to which fuse it may be on these pictures of the cover? Like what would it be called? Thank you for your help. Cheers

Never heard that one. The first thing we normally do is replace the vent solenoid. Sure, you can test it with a scan tool or with a test lamp and voltmeter but why bother?

Had to look out of curiosity, power from TCM-BATT fuse.

ECM grounds it.
