    My 2019 CRV gets CEL codes P0455 and P0456 when the gas tank is about half full. I fill the tank and can clear the codes and they stay off until the gas tank reaches about half full then they come on.
    I have tried cleaning and lubricating the inner and outer spring loaded fill doors as best as I can to no avail.
    Any ideas to the possible causes of these CELs?
