My fuel gauge has been inconsistent for month's. Sometimes it indicates a full tank when I know there is only a 1/2 tank. This morning while at a stop light I heard the low fuel tone, the fuel light was on and the gauge indicated empty.
I shut the truck off then started, know its completely full.

Pulled a code p0460. I looked it up several times but it all goes back to the 6.0.
Any ideas before I start looking into what my 2003 7.3 might share with a 2003 6.0.
Thank you JPC

Here is your code

P0460 Fuel Tank Level Indicator Circuit Malfunction

Your tank float could be stuck or bad. The sender is more than likely the culprit though.

Thank you for the reply Woodnthings.
I have pulled the tank since this has been happening. The float was working properly at the time.
I agree with the sender sense it is working properly, totally full or completely empty.

I will look into a new sending unit now.
Thanks again

Here are the four probable causes of the Fuel Level Sensor Circuit Malfunction code, in no particular order.

1: Open/short circuit
2: Cluster
3: Tank unit
4: Open case GND

When you dropped/raised your tank, did the wires get tugged? I agree with above, that it may well be the sender unit but I would test/check others first, since it doesn't cost anything.
