Default OBDII Fault Code P0463

The other day I was driving along and I heard a large thump sound. It sounded like it came from the roof but a visual inspection showed nothing. Around that same time, a check engine light came on and lead me to believe maybe it was something under the hood? Can't say for sure if it was related.

Anyways, I plugged in my OBDII scanner and up popped this little gem:

Fault Code P0463: Fuel Level Sensor Circuit High Input

There is information on it here: P0463 DTC: Fuel Level Sensor "A" Circuit High

and here: P0463 Fuel Level Sensor Circuit High Input


I have noticed sometimes the fuel tank meter jumps to low (like three pegs) and then jumps back up to half a tank.

This car is brand new and only has 951 miles on it. I have been following the break in period rules and I'm not sure what that load sound could have been. Taking it to a dealer on Saturday to get this straightened out.

Just wondering if anyone else had similar issues with this code on their Z?
