Default Fuel temp sensor

I have a 2001 2.5rs wrx swapped and I’m getting a code for high voltage input fuel temp sensor or something and on my cobb it says the fuel temp is at a constant -40 does anyone have any info on this or how to fix it

Mess with the fuel pump assembly lately? The -40 could be a default value that the ECU uses when it can't find data that makes sense. If the voltage is high, that could indicate a short in the temp sensor.

If you have the GC fuel pump sending unit, it will throw that code because the wiring is different from the GD
