P0463 Fuel Level Sensor Circuit High Input

Started my car yesterday morning and this pops up immediately. Car drives fine. I just installed the Scantech software and used the Tactrix cable to read and remove the code. Started the car back up and it hasn't come back yet.

Just wondering if anyone had experienced this code and if so had determined what might have been the cause.

Thanks,

Tony

BTW the car has a little over 20K miles and the mods listed below with a road tune EcuFlash by William at Precision R in San Antonio.

 

Tony, did you get any answers for this?

I just got that code on my <1kmi fully stock IX MR. Read it with Alex Peper's obd-2 setup.

 

Just to follow up, I had the car in for service but the techs were not able to identify the cause. They cleared the code, and we'll just have to wait and see if it happens again.
