Strange smell from rear end outside.

I can smell something similar to gasoline when the vehicle has been idling for a while. It’s clearly noticeable when standing near the rear end of the vehicle. Could the Evap error codes large and small lead to this codes 455 and 456 I recall also have a bank 1 or 2 o2 sensor error code. But had these a while now. Thanks

P0455 is a "gross leak" code, meaning something at the evap or tank is wide open to atmosphere. If it started with a P0456 then you may have an Evap Vent Valve that's stuck wide open, or there may be something broken in the plumbing.
