I've been getting the P0455 code and have replaced my fuel cap but still smell gas and getting the loose fuel cap warning then a few miles later the Service Engine Soon light comes on and stays lit. I wanted to try and replace the EVAP canister vent control valve and see if that would fix it. I spent some time under the car today and could smell gas and found the EVAP Canister Filter but not the EVAP canister vent control valve. From reading the service manual you have to remove the gas tank. Is that right or is there a easier way to get to the EVAP canister vent control valve? This is a for a 2011 Maxima SV.
Thanks

Thanks, that is the service doc I was looking at for the fuel system but it does not show the location of it in a diagram. It only states that you have to remove the rear stablilizer bar first. Is there anyway to get to it without this?
