Fuel Gauge Acting Wacky? Need Help?

[baycountry16]

So I bought a 2006 F-250 PS King Ranch about 3 weeks ago. Been running great, but today for the second time since I bought it, the fuel gauge started going haywire, I had 260 miles to empty this morning. While I was driving the screen dropped down suddenly to 180 miles to empty. Then it dropped all the way down to low fuel indicator, and then went blank. Then the check engine light popped on and a message appeared saying " fuel sensor error " or something to that effect. A few minutes later, the needle went back up to around 250 miles to empty. The needle seems to be working fine now. My questions are: Should this be of concern? How do I get the check engine light to go off now that it is working properly again? Any help would be greatly appreciated

try some of the chevron fuel additive, it fixed my gauge issue. It's been so long I think it's called stanadyne. just found this also dieselmann's editorial

My 06 does the same thing. It is the Fuel level sensor, which is in the tank. Mine only does it at idle, but the guage will go to empty, ck engine lt will come on along with low fuel message. The codes are for fuel level sensor voltage too high and fuel level sensor voltage too low. I get both codes. The gauge usually starts working again once I drive it and hit a few bumps, so I just clear the code and live with it. Not worth the $600 part in my opinion.

Thanks for the info. Do you know how I can clear the code to get the light to turn off? Will it go off itself after a few cycles of driving per the owners manual?

I just clear mine with my SCT. I'm not sure if it will clear itself after a few drive cycles. Mine does this about once a week, or every two weeks, so don't know how many drive cycles the computer needs to see, but I'm pretty sure mine never has a chance to clear itself as it never makes that many drive cycles before it happens again.

yeah, my first purchase is going to be an edge insight cs once I get some cash, then I'll be able to clear it myself
