Yamaha PW-ST has no speed or power flashing function display

[Sammyg]

I have Yamaha PW-ST that has no speed displayed, and the function field flashing, motor works in walk mode, and seems to have basic power to about 4 MPH, I did move the senor a few days before the problem, and it stop walking on a very wet and cold ride. I have put the sensor and magnet back to stock, and the sensors read correctly in the diagnostic mode "d1"

Any advice is greatly welcomed.
