Speed sensor power

Briand221 · Oct 22, 2022

Where does the speed sensor on a 2022 monkey get its 12v power from?
Tried to fit Healtech speedo corrector and had 11.1v power, ground and 4.6v to the speed sensor
Now I’ve lost the 11v supply to it but the other 2 still read the same.
healtech have given me another option to wire in to the front of the bike but need to sort the original power first before doing this.
speedo just reads zero 😔

It’s the white and green that’s no longer getting power even though the ABS module seems to be working as it’s giving no faults on the dash.
All fuses have been triple check so not sure where to go now?
Thanks for the help 👍

I suggest you download the service manual from this forum. There is a complete diagnostic guide to the ABS system starting with the fuses of course but getting fairly complicated.

From a poor quality wiring diagram it looks like a white and green wire should be 12 volt. If its an ABS version it comes from the ABS controller for non-ABS from the instrument cluster. Pink wire carries the signal. Green wire is ground.
