I have an issue with my 2000 Honda Accord and it just started popping up
over a month ago. The problem is that my check engine light comes on at
random intervals, yet, every diagnostic stated that it was related to the
I am getting tired of bringing it to Autozone and the Honda place and being
told to let the fricking gas cap click three times after I fuel up (I know
this and I do it already). Is it possible that this sensor is bad because
this is the fourth time in a little over a month that it has come on yet
again? FWIW, it doesn't even come on after a tank up, nor does it matter
how much fuel is in the tank. It just comes on, and it ALWAYS is fuel cap
This is really starting to annoy me!
You don't state the codes and fuel cap related doesn't do anything to
resolve the problem. there are several codes in the EVAP system and there is
extensive troubleshooting charts in the service manual. If you plan on
fixing it yourself buy the manual or take it to the dealer and tell them to
fix it right and stop guessing. Of coarse replacing the gas cap and
inspecting the whole gas/evap system for damage should be your first item on
Any leak in the vapor side of the fuel system will bring in this code; it's
just that the fuel cap being loose is the most common reason on cars that
aren't old enough for the rubber stuff to deteriorate.
I failed emissions two consecutive years with my '85 Volvo because of
failure of the fuel system to pressurize. Each time it was vapor hoses that
had cracked in forsaken places, and I found them by rigging up a bicycle
pump to a vapor hose.
In a 2000, the most likely cause of a leak that isn't simply an
undertightened cap is a bad cap. A replacement cap is a cheap price for
being at least able to rule that out. As another posted, it can also be
filler neck trouble, but easy things first....

Chris B, did you ever get this sorted out? I have a similar problem,
so I am interested in a simple fix if possible. The check engine light
is staying on, and Honda repair garage says there is a sensor in the
tank that when you overfill the tank, the sensor is damaged. They want
$350 to replace the sensor, color me skeptical please!!!! A new fuel
cap sounds a whole lot cheaper.
I've found that to reset the light, you have to disconnect the battery
for a few minutes to reset the computer also. Have you found anything
along these lines.
The car continues to get good milage, and passed a recent emission
test, so I find it hard to believe that the problem is serious, but
the light is annoying. Tinkerntom
With my 99 Accord I didn't need to disconnect the battery to reset the light
& computer. I just pulled the fuse for the dome light & clock (passenger
side of dash on side). My problem ended up being the Cat. Honda wanted over
$800 just for the Cat so I bought one from Summitracing.com for about
$140.00 and it has been fine now for almost a year.
