According to the Deere TractorPlus App, it is:

Enable pressure sensor voltage below normal, or shorted to low source.

The power reverser transmission pressure sensor reporting the low sensor voltage is located on the left side of the tractor under the operator work platform.

784701


The first thing I would do is make sure that the sensor connector is still securely plugged in and verify that the wiring and connector going to this pressure sensor hasn't been damaged by a stick or something.

If you want to do some electrical testing, you can remove the connector and verify that the pin connected to the purple wire (sensor power) has 5 Vdc on it when comparing it to sensor ground on the black wire.

Does this error never clear on its own?

Thank you very much… a new sensor solve this, maybe a stick had broken it.
