Fuel sensor? - Honda Prelude Forum

I think I am having a problem with my fuel sensor. It doesn't always register right on the dash. Cuz one night I filled her up and drove around everywhere then I raced then drove some more and my fuel guage on my dash still said I had a full tank. Is there a way that I can fix this problem?

This is actually normal, I can drive 50-75 miles before the first bar turns off. Virtually every gas gauge is engineered like this (and dumb people are to blame.)

Oh really? Okay then

Yeah, Mine is the same also

yup, i think the first bar goes down after 50 to 70 miles

The reason for this is a gas gauge works but a thing that floats in the tank. The thing that happens is the think floats to the top and hits the roof of the gas tank before the tank is completley full. So a few gallons have to go out if you fill up all the way before it will read gas missing. The same effect happens on the other end. Your gas guage will read nothing when you sill have some fuel left. The most I have pushed it is maybe 20 miles w/0 bars.

The gas gauge is designed that way. People want to be fooled into thinking they are getting good gas mileage. Even if it means that last 1/4 tank flies. Car and Driver did a story on this and when Ford made a truly accurate guage people complained of "poor gas mileage." This perception was based of course on a fuel gauge that wasn't lying, they didn't actually measure MPG. And duh, of course they build in a conservative margin when the tank is on "empty." Repeat after me - people are stupid!

What I am talking about only happens on reading completely full or empty. BTW I think the gauge moves down correctly from f to e.

Then you'd be wrong, and you're one of those people who like to be fooled

he means full isnt really full and empty really isnt emptire but each bar is equal to all the other bars. how far can i drive when im on e?? like when the gas light comes on how far can i drive?

I think mine is truly screwed up it will show like half tank and the fuel low indicator litght will be on. Can this be repaired?

L-U-R-C-H · 09-05-2002, 09:57 PM

Yeah, can that issue be repaired?
