Po463

Fuel level sensor circuit high input.
Wife just got home from a road trip.
She said she started the Commander up and the fuel gauge read empty even though it had a full tank and had a check engine light.
Shut it off and started it again and then the fuel gauge read full but it still had a check engine light.
She was driving home and again the fuel gauge read empty and the warning light came on for low fuel.
Stopped and put in 3 or 4 gallons of fuel.
Gauge again read full.
I ran a code on it when she got home.
PO463.
Jeep runs fine.
From what I can find on searches it could be a grounding issue.
Anyone know where the fuel level sensor gets its ground?
Other than that it could be the sensor itself, which I issume is in the tank.
Anyone have this problem and did they fix it?
06 Jeep Commander, 4.7L engine. All stock.

Here is a link from 2006 if it helps.

http://www.jeepforum.com/forum/f9/co...3-what-901522/

Had a similar issue as my gas guage was not reading accurately.

Dealer replaced part number 51613335ad under warranty.

Problem seems to be resolved.

It looks to me like that part number FROM 06 has a typo but if you look at this page it has reference to similar part #S.

I also read that like you mention could also be corrosion at battery or gnd connection at sensor as well. I would try re-booting (disconnecting at battery and cleaning that first) sorry can;t be more help.

Ya I tried disconnection the battery and cleaning the posts. I also cleared the code.
There are also some grounds right next to the battery. I cleaned those also and made sure there was metal to metal contact.
It happen again not long after cleaned them up.
I am going to drop the tank and replace the fuel pump and module.
The Commander has 140,000 miles on it. Who knows how much longer the fuel pump will run anyway.
It will be a couple of weeks before I do but I will post up what I found.
Thanks for your help!
