I overfill gas tank on my Prius V 2012 and now have codes sowing up: P043e P043f P2401 P2402 P2419 Even if I clear the codes they will comeback after a day or two, triggering engine light. In addition, gas station fuel pump nozzle is triggered when I pump the gas too fast. I think I'll have to replace the charcoal canister. How hard it to replace it? I don't have any car lift, only a ramp.
