Low Fuel Indicator

Something weird happened today. I put $20 worth of 91 octane fuel in the tank today which took it to almost half a tank full. I drove to Napa and back and the low fuel indicator came on when the needle was just on 1 quarter tank full. It usually comes on when it is barely touching "E". Anyone knows what the deal is? I hope my Edge isn't causing this problem. Thanks.

Yes...I was actually driving when it came on.

I think he was asking if you had the key on the on position while filling your tank.

My sensor is messed up too, has been since I drove it off the lot. I have a 27 gallon tank, but my warning light goes on at 7 gallons left, and my gauge will read absolute empty with 3 gallons left. It's not a big deal, but it annoys the crud out of me. She's due for a 20k checkup in a few months, and I'm going to have them take a look at it then. I'm hoping it's just a calibration issue, and not a bad sensor, considering the sensor is mounted inside the tank.

No, the keys were in my pocket.

OK, there is definately a problem with my electronic fuel guage. The needle seems to be working fine and the speedometer seems to be working fine. According to my speedometer, it is only 2 miles from my house to my gym. During that 2 mile trip, the "miles to E" guage went from 40 to 34! My concern is, once it gets to "0 miles to E", will it send a signal for my engine to shut off or will it go by the actual needle guage? Any help would be greatly appreciated.

The engine won't shut off, that's just information for your use. It almost sounds like there may be a ground that loosened up somewhere, since your problem seemed to happen all of a sudden. It could be something super technical, but never underestimate the effects of a bad ground.

Thanks for the info...that eases my concern somewhat. Now I have to find time to take off work to send it in to the stealership!

No problem. I mentioned it may be a ground, but it's more then likely the sensor. That's how electrical components are, one second they work, the next they don't.

Time to go burn up some warranty!

Isn't the sensor inside the tank?!

As far as your problem goes... it is probably normal. The fuel is used to cool the fuel pump and they might set low fuel sensor so that there is that much fuel in the tank to keep the fuel pump healthy.

Mine will have the low fuel light come on with about 5 gallons left in the tank some where between e and 1/4 of a tank.

Yes, but why worry, you still have warranty right?

Yeah, but I was thinking would be a 2 day job. Maybe not...I don't know.

Mine used to do that, but like I said, it came on at 1/4 tank yesterday which is not normal. It's a pain hitting the reset button every time I get in the truck.
