How can I reset Fuel Range readout?

if im not mistaken- once it gets low on fuel--- it stops displaying approximate distance and then just shows-- FUEL LEVEL LOW.
But- I changed my fuel pump out- (pump and level sender)- with parts and doing it myself- the price was about $350.
I called a local dealer and he wanted about $1200.

I wrote up a how to.... to see the missing pics--- look at my gallery....

I get "RANGE LO" on mine when it's at red line, but the sender is still good because the gauge still reads accurately.

Is your gauge also reading poorly?

Don't trust the gauge OR the DIC readout if you have a flaky sender. Start using one of the trip odometers and be conservative and fill up after the miles traveled gets to near what you used to get out of a tank.

The readout is incorrect. it says i have 40 miles before tank is empty. However, at that point, the tank is empty. I found out the hard way on friday when i ran out of gas on the highway.

dealer said the sender is bad. I just didnt want to have to change the sender if i didnt have too. if i could reset the readout it would solve my problem.

the analog gas gauge works, so it the digital doesnt really matter, im just being fussy..haha.

On a well-running system, you might get the RANGE: 40 display when the analog gauge is at red line. Then the low fuel light goes on, it dings at you, the DIC goes to RANGE-LO, and the analog needle ONLY THEN goes below the bottom of the scale. Most of us don't physically run out until the analog needle is significantly below the bottom.

If you ran out of fuel, and the analog gauge had just arrived at the bottom of the scale, then the sender is definitely at fault. And once it starts going bad it never recovers.

The algorithms are baked into the software flash memory, and aren't editable or resettable by users like us. I've never even seen it in a table accessible by tuning software.

Or you can use the digital fuel meter in the DIC, which would be more accurate than the odometers regarding fuel consumption.

Just :m2:

Yep, fuel sending unit. The price sounds about right too. The dealer quoted the sending unit at about $700.00, but since it is under warranty only cost me $200.00
