I can only tell you that I just kept going back to the Honda dealer and after they replaced the solenoid valve it was fixed, but the first fix was with faulty parts. It would seem HONDA is aware of the problem and maybe there are a lot of faulty parts out there, just keep going back. I know its annoying, I was furious everytime I left and filled up and then got the stupid error, but it did get fixed and if they dont fix it after 3 vists then take it to lemon law. When I went in on the 3rd time, I told them if it wasnt fixed then I would go to lemon law to sort it out, it was then fixed. So if its not fixed 3rd time, go to lemon law as they have to fix it and it may be the dealer that is screwing you and not HONDA USA.
