Hi all. Been reading for awhile and found lots of useful info but now facing an issue and not finding a while lot of info. We have a 2010 Expedition EL flex fuel. My wife was driving a couple days ago and the CEL came on. The code was P0461, which I understand is a fuel sensor, which explains why it started reading empty even when I filled it up. The miles to empty also reads 0. I really don't want to drop the tank if I don't have to. I'm hoping it may be the wiring harness, but a am unable to find it. I thought it would be I under the drivers side door on the frame rail near the fuel filter (similar to my 2002 expedition) but I didn't see it. Wondering if anyone had any thoughts or suggestions old things to check before dropping the tank.

Thanks.
