OK Ian, we are only trying to get the written fact that will help us to help you, so the ! really is surplus to requirements.
Moving forward:-
Run diagnostics again to confirm that the front wheel is still the only offender.
If so, check and trace wiring to sensor. Incidentally, what make sensor/s did you buy, and did you fit 4 of them?
If wiring traces OK, consider other options such as rear wheel ‘senders’ which are built into the hubs.
Finally Ian, we are not the Spanish Inquisition, but we do need facts to help, and being helpful is our only aim.
Please come back to us with what you think.
Kind regards,
Gareth.
