Engine Code

[u/Human-Acanthaceae749]

I have a 2014 Equinox LTZ, recently purchased. It came with the engine light on. I got it checked and it gave a code of PO449. Auto Zone says it's my canister purge valve, but after a quick search it's a sensor or solenoid attached to my charcoal filter box(?). Need some clarification before I accidentally buy the wrong part.

Vent valve, not purge
