Error Code 12

[Forrest1357]

I just got an error code 12 on my JD 3720. Manual says its a stuck sensor. Does anyone have any ideas before I take it in to the dealer?

Looked at my book on 4520 says sensor supply voltage. And the tractor does not operate.
What does your tractor do.
Maybe a dealer problem

From the 3X20 technical manual.

Err 12 Sensor Supply voltage
Voltage is out-of-range.
Machine does not drive.
Check the 673 series of wires and connections for a short or open circuit.
