"Sensor voltage low" means that there is a short to ground somewhere.... [pulling the voltage down]
If a wire is broken or disconnected it will throw "sensor voltage high"
So I assume there is a hyd cooling fan motor, in which the speed is controlled by a solenoid...?
And is there a temp sensor somewhere in that area aswell?
Typically sensors use a 5 volt or 7 volt reference signal from the computer.
This is relatively low current also, small wires [delicate]
If there a few different connectors in the vacinity, try unplugging them one by one and see what code develops... it may guide you to the circuit that is giving problems
If you unplug one and the code changes [without an additional code] at least you know what set of wires to trace.
Keep calm and combine on....
