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.
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?
