the speed sensors connect to the ABS and Tranmission computer and to the ECU. I'd look into the symptoms of a failed ABS controller board. Not sure about your model year but its a common fault area for 2000 vintage Volvos where the solder joints in the ABS board crack and cause errors and codes.
Google Midwest ABS and RochaTek for details.
