So , I was out of town 7 days. The day after I got back I started up the Camaro to let it idle for a bit from the sitting .. upon driving around the block the check engine light popped up . Car ran fine with no signs of any issue . I got to work on Mon, and borrowed my coworkers scanner to show me the PO449 Evaporative Emission Control System Vent Valve/Solenoid Circuit code. This surprises me at only having a lil over 32k on the clock.. I cleared it , but on the way home it popped up again.
My question is , what part exactly is this code for? I checked the gas cap , as cap is fine. Is it a charcoal canister or solenoid ? How much does this usually cost to fix?

It's usually the purge valve.
