The speedometer doesn't work. With the electronic dashboard the electronic speed sensor is used.
We also should replace this sensor. There is it on a gear box.
We disconnect wires and we unscrew the sensor. For this purpose the key on "22" can be required.
After replacement of the sensor the speedometer earned again.
The speed sensor is based on Hall's effect. I tell about it in this video. Look and subscribe for the port!
