Default ABS code C1233 R F Speed Sensor open or shorted with ABS and TRAC OFF lights on dash

Have a CURRENT code of C1233 showing problems with the right front ABS sensor. Also have following history codes:
C1216
C1222
C1226
C1233
C1275
C1298

The ABS warning light and the TRAC OFF light are lit on the dash and pressing the TRACTION button on the console does nothing.

What is wrong and what do I do to fix it?

Default Open wire 3 inches from wheelwell connector

Took a week to find pinouts for the ECBM ABS connector and 2 hours to trace and fix the open wire/

Hello Sir

I think I have the same issue on my Regal 2003 since the city towed it few months ago...

the brakes have been replaced and they are brand new in front and rear and it brakes up well

so I wonder if it is only a connector to fix ??

Do you have the steps to perform to fix it please ?

Is it kinda easy to find that or should I still try a car dealer ?
