Unhappy "Loose Fuel Cap" light

hey everyone,

Noobie here, but I've had my fit since June 07 (15k miles or so on the clock).

Anyway, I registered and did some searches but couldn't come up with anything... hopefully you won't shoot me for asking this.

A "Loose Fuel Cap" light started flashing tonight, where the odometer usually is. I think it says "check loose fuel cap" or something similar. I checked the cap, twice. Unscrewed then screwed it back on. But nothing. There is 1/2 tank gas in there right now. Shut off the car then started her up again. Still the same problem. I could not find any threads on this but hopefully someone can help. Has anyone else had a similar problem? I may try to wake early and head to a nearby dealership before work. Maybe the light will magically disappear tomorrow. Who knows.

So anyone able to help at all? Seen something like this before?

Thanks all.

unplug your battery and wait 2 minutes. then plug it back in and turn on the fit. this should reset the ecu and the light should go away. make sure the gas cap is on tight too. listen for 3 clicks at least.

Put some "Vaseline" on the seal of the gas cap. then just wait for 40 key cycles or less. the computer will continue to monitor it. If it sees the problem is fixed, it will turn off the light.

if/when you do this, make sure you have your stereo key code on hand. when i installed my intake i had to remove/adjust the battery and it asked for my key code when i plugged the battery back in and started it up. i didn't know WTF the key code was so i frantically searched through my dealer papers LoL

My Fit has thrown the "Check Fuel Cap" once before. I stopped twice within 30 minutes to make sure it was tight.
The notification was gone the next day.
Odd.

Is this with your manual or located somewhere else with paperwork? Just so I know for future reference.

the radio code should be on a separate piece of paper that the dealer gives you.

it's on a separate card that's about the size of a business card. mine was plastic sealed and attached to the stereo warranty guidelines/dealer BS.

Slow Fuel Cap Leak

Mine did that too…an 07. I called my friend at the Honda dealer and he told me to turn off the car and then start it three times…that clears it. No radio codes to re-input either.

As for the Vaseline…ArmorAll does a much better job…and not as messy!

My 'check fuel cap' warning came on when I started home from work last night ~ about 240 miles since my last fill up (2007 MT Sport ~35000 miles). I stopped at the dealer and they reset the computer. The service fellow said sometimes serious sloshing might trigger the sensor. I did make a more rapid than usual sharp turn exiting the parking garage just before the warning appeared. I'll keep an eye on it.
