Getting the dreaded P0445 dtc on a 2010 Impala 3.5l that i need for work and i have yet to pass the emissions test. Save me lol.

I saw a service bulliten online for replacing the purge solenoid under the hood so i replaced it.. no luck. I know there is one under the car by the tank but i haven't gotten to that 1 yet. Besides vaccum line leaks or the gas cap seal is there anything that would cause this?

definitely check the canister vent solenoid. just about every impala that comes through with that codes ends up needing it.
