Hi,

I have a 1999 Yukon Denali 5.7L that is throwing the P0446 code and SES light is on. I have looked everywhere under the truck and cannot find the evap canister, vent solenoid or anything that resembles them. Does anyone have an idea of where these parts would be located on my truck so I can check and see if they are blocked or bad?

 

Thanks in advance!
