2003 E500 P0446
Hey guys a while back I purchased my 03 E500, the car needed a bunch of work but I finally got it running really good. I use to notice once every month or so car would kick out a P0456 (small evap leak), so I replaced the gas cap and I haven't seen the P0456 in several months. But today I decided to take the car out after letting it sit for a week, it set off the P0446 and P0456 code. I tried researching the location of canister shut off valve and the charcoal canister, but have had no luck locating on the car or in any technical manuals. If you have and idea, pics or general troubleshooting knowledgeable on the code P0446 and P0456 please post what you may know thx

I think the biggest problem I have is the location? I looked under the hood, removed lower body panels and fenders if there was a picture of what the shut off valve and canister looked like it would be helpful

THis is located in right rear wheeliner area.... IF you have new part, remove rear fender liner and you'll see where it goes. Can be a pita to install though! good luck.

Hard to install the valve or the charcoal canister? The car set off of the P0446 code, I was going to try replacing the valve first. Is the valve located in the right rear wheel liner?
