I got the P0456 code on my 2010 5.7L hemi a few weeks ago. I replaced the gas cap and the code is still there. I'm pretty sure the issue is with the purge vent valve. I have the part in hand, the only issue is I can't locate the damn thing to replace it. I have watched a lot of youtube videos on replacing these but I have not found one for my make/model specifically. It seems like they are either under the hood or on top of the gas tank from the videos I have watched, but I can't find mine. Any help is appreciated
