Bosch cx gen 4 523001 error

[Hattori-Hanzo]

At BPW for the weekend and typically the bikes throw up an error, 523001 speed sensor error.

I've checked the magnet and connectors into the kiox and remote, all seem okay.

Is there anything else to check?

Other than that is it a warranty job

Maybe check the connection to the motor and the integrity of the full length of the speed sensor cable?
I’ve found a cable on a shimano motor looking like this
