I recently have been having issues with my fuel gauge being stuck fully up and a constant code P0462 fuel level sensor circuit low input. When it occurred was when I had just topped off my tank and then went home and jack the rear of the car up a little to put in a little diff fluid. When I put it down the code popped up and the gauge was pegged. I took it out and tried cleaning it and putting it back in and still nothing, I even when over some un even surfaces to see if it would unstick and got nowhere. I've been driving for almost a week now, is this common?
