Error Code P0460 fuel level sensor circuit malfunction

[BlacknCream]

Found this code tonight, fuel gauge has been giving me issues (staying on full) After filling the tank and riding 18 miles the sensor voltage shows .87V. I remember reading somewhere what voltages are supposed to be but I cant remember where or exactly what they are supposed to be but I was thinking the low fuel light was supposed to be lit at 2.3V and when I was looking around with tuneECU when i updated the map awhile back it was showing about 1.83V with around 2 gallons left in the tank. The gauge did begin having the issue when i updated to a custom 20220 map to match my No Cat stock pipe setup.

Any ideas or info will be greatly appreciated. My bike is an 07 classic btw.

Have you checked that the float is not stuck?

As the fuel level changes the sensor voyage is changing at the ecu but doesn't seem to be changing art the gauge.
