My camaro keeps ringing code P0455

What does this mean to fix? How long will it take and how much money for it?

Might be the most common code in the world...

Loose or damaged gas cap? Debris in the threads of the gas cap or filler neck causing a poor seal? If no gas cap on your car is the capless filler neck damaged?

This should be covered under warranty unless you have voided it with mods.

Interesting. It popped up after the first time I got gas in it. Sorry for the dumb question this is something I’d ask my dad if he was still around.

On the SS, it serves as a reminder to the crank horsepower rating.

No worries.

The only dumb question is the one you don't ask - which often leads to trouble down the road...

If the code keeps coming back it could be a bad vent control valve. Let the dealer take care of it as it should be a warranty issue.

Since this happened the first time you fueled, I would check the flapper door on the fuel inlet to make sure it's sealing.
This is a "large leak" code. Any smell of gas around the car, under the hood?
And, of course, has the car been modified? Any messing with tubing under the hood, stereo in the trunk? I think there was a post where someone did a subwoofer install and drilled the vent line. So gotta ask these questions.

I haven’t messed with anything. Took it to the dealership today and they found no problems with it thankfully.
