  • Flashing fuel level indicator gauge?

    Good Afternoon fellow cngers,

    Just curious to see if any else has experienced the following, the fuel level indicator flashing nonstop, I have tried to cycle the key between on and off but nothing.
    I don't know what this means so that's why I am reaching out to yall!

    Thanks...

      Scott,
      that seemed to do the trick, although I had looked at the door earlier and it was closed but I suppose I did not lock it all the way, so thanks fo the input...

        honda service center in torrance has tried several times to fix that same problem in my 07 GX; the fix usually works until the next time I fill up. :} so far they don't know why it's happening.

          I had that problem with several new '07's after fueling them for the first time. You can obviously have it taken care of under warranty, but if it is driving you nuts and won't stop, pull down the cover (liner) enough to see the back side of the gas door from inside the trunk and unplug the sensor wire that reads the fuel door position. It's designed to tell you if you forget to close the fuel door. I don't remember what my tech said was causing it but they ended up replacing something that I would never have associated with the fuel door to correct the problem.

            Jim, call Alan in my Svs Ctr and ask him what they did to fix the one's we encountered. Use the # under my picture. If you only try and bend the tang on the fuel door... it comes back.

              Not sure about the generation VIII civic GX ('06 and later) ,

              But on a generation VII GX, ('01-'05), a flashing low fuel indicator means the computer is getting either an open, or shorted fuel tank pressure sensor indication .

              This info is from the GX service supplement manual.

                If you have a later model which has the 'fueling door open' warning, here's what helps.

                Open the fueling door, with the ignition on, and reach where the 'elbow' of the fueling door would push if it were closed. There is a small switch. depress it to see if the flashing warning goes out. If it does, but doesn't go out with the door closed, it needs adjustment. I had that issue and just added a layer of speed tape (small piece of duct tape on the 'elbow' to push a little more on that switch) and it was enough to solve the problem. Where that switch is makes for the need of a fine adjustment, which appears to require access from behind the rear seat. I wan't about to fiddle with that.
                I'll have the tech's do it at my service.
                Hope this helps,
                Jeff

                  That flashing gauge is also a great warning to avoid driving off with the hose still connected!

                    On the 98-00 GX the flashing low fuel light meant that there is a leak or major malfunction in the CNG system I believe. What year car are we talking about here?

                      I have the same issues with mine since I literally test drove it of the lot and drove it home. It was fixed while we were signing the papers so I thought, 3 days later BAM it was back. Brought it in to get it fixed, all is good unitl I brought it in for my first oil change. Don't know what the heck they did, flashing lights were back on the way home.

                      Brought it back again, though this time it wasn't flashing. usual dealer response "well we can't fix it if we don't see it". Left the darn place feeling frustrated, I haven't had time to bring it back, but it's getting real annoying. It seems to be more consistent now, everytime I start the car it seems to be doing it. Though she does stop after about 20 minutes or so of driving.

                      Honda must know of this issue, gotta be some software or firmware deal?

                      BTW, anybody have any luck disabling the auto locking feature. The dealer could'nt figure it our either.

                      It's still flashing BTW

                        Read the first 2 posts I made in this thread. My svs writer has run into several of these, all 07's. Alan can probably tell you over the phone what the problem is. I also listed a quick fix to keep it from driving you mad.

                          A flashing gauge on an '07 has a dual purpose. If it flashes and the gauge is reading the level correctly, the door is open. (or switch mis-adjusted, broken, etc....)

                          The owner's manual says if the gauge goes to zero and flashes, get it into the dealer, there's a fuel system malfunction.

                            Curtis,

                            When I brought mine in a couple of months ago, Alan said there's a sensor in the wiring harness that needed changing.

                            Mine has worked fine since.

                              Ok so my 2007 Honda Civic was parked in a steep driveway tonight. I get in to leave and my low fuel light was flashing and the gas gauge was down to no lights within 45 seconds. And honestly I am freaking out. I read in a thread that disconnecting the battery may reset the codes but won't it throw the code again later on? I'm sorry if this sounds dumb. This is my first CNG car and I don't want to have a 3,000 parts and labor bill after Christmas.
