We have a 2011 Lincoln Navigator THAT RUNS FINE and we had a Check Engine Light that gave us a PO461 (Fuel Sensor Issue).  I cleared the code hoping it would not reappear.   What then happened was our Fuel Gauge went to EMPTY (Even though the car has almost a full tank AND the miles to empty now display "--Miles to Empty" now.  Of course the sync system now displays gas station icons on the map since the car "thinks" the car is empty. Is there a relay of fuse that blew?  I can't figure this one out and appreciate any help I can get.  I have searched the web and seems everyone that has this problem gave up and just uses the tip meter to see how close they really are to empty.  I would love to have this working again.  Thanks to all in advance.  Love Scotty's advise over the years!!!
