Fuel cap and persistent check enine light error, 2008 Honda Civic LX

Hi bought a new 208 honda civic in November, recently I got a check fuel cap error, of course I did and its fine. Then the check engine light came on so i went to the dealership. The error code indicated a vapor leak, but they could not find one and reset it. Then a few day later I get the check fuel cap error and then the check engine light. So I again return to the dealership, again the error code says "SMALL EVAP LEAK DETECTED" and they ordered parts i.e. EVAP CONTROL CANISTER, so I returned to have them install this and the test indicated it was all normal. So I then go along and you guessed it this weekend I get the check fuel cap error and then the check engine light. So now I am back having to go to the dealership, it is a pain in the behind for sure. I note that it seems to happen about 2 days after I have filled up the car and I always check the gas cap to see if its on properly, any one have any suggestions??

I know it's a pain to take back to get fixed...but that is exactly what you need to do. They'll continue replacing the parts that could be causing the problem until they finally find the right one. Don't live with this problem out of frustration, because it will be very expensive for you to fix outside of warranty. Let them continue replacing parts till they get it.

Do not overfill the gas tank, stop at the first click.

Sorry, I don't have any suggestions, but wanted to say that I think I may be starting to have the same problem and would also be interested in the solution. I bought a 2008 civic a couple weeks ago. A couple days after I got it the check fuel cap message came on. I tightened the fuel cap and after a day or so the message went away. Then, just yesterday my check engine light came on (like you, it was a couple days after I got gas). I always tighten my gas cap to at least like 5 clicks after I get gas so I don't understand why it would be loose, but it did seem to tighten a tiny bit yesterday when I turned it. I'll be curious to see today if it resets itself and the check engine light goes off now. If not, we'll be making a trip to the "stealership" monday. Or if it happens again I'll also take it in. I hope I don't have to make as many trips as you though!!! Let me know if/how they finally fixed your problem!

Hey, so after my first post above I went to the dealer and they couldnt find anything wrong. They called Honda tech and they said that the parts they had installed were a faulty batch, so they had to order (more) new parts and replaced it all. The parts they replaced were: the Purge Control Solenoid Valve. Since then it has been fine, but believe me when I filled up the first time and drove home I was waiting to see if it came on. If the check engine light comes on after the check fuel cap then you will need the dealer to reset it, and be sure stop filling when with gas when the pump stops,i.e. dont top off and and at least 3 clicks to tighten. I know you know this but they will ask you this repeatedly at the dealer, so you can be sure u did right!

I have the same exact issue. My dealer just keeps resetting the code and tells me that they can find nothing wrong. I only pump the gas until 1 click and then stop. I still get the Fuel cap message. When will Honda step up to the plate and get this fixed? I bought a new car just so I wouldn't have repair issues.. I hope it does not start affecting my MPG at today's gas prices.

I will check back every so often to see if there is a fix. Thanks.

I also never overfill my gas tank (I don't "top it off" after the pump turns off the first time). So... to follow up on my previous post: My check engine light never reset itself so I took it to the dealer. Apparently they found a TSB that was just put out that day for the car (March 6) that supposedly told how to fix the issue (I have done a few searches though and haven't been able to find info on this TSB online yet... maybe it's too new?). They replaced the "EVAP PURGE CONTROL VALVE" and reset my check engine light. I thought it would be fixed...
3 days ago my check fuel cap message came on again... I tightened it and it reset overnight... Today my check engine light came on again. And it still starts really rough some days!!! So frustrating when the car is less than a month old...
Does anyone else have a rough starting issue (sometimes cranks for up to 10 seconds before it will start) along with these error codes?

Hi again,

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.
