Im getting a code for a rear speed sensor but the bearing is still good and i dont like the abs so i was wondering if i could disable it somehow?

 

ABS Sensor Replacement | ABS Wheel Speed Sensor | ABS Brake Sensors | Anti-Lock Brake Sensor At 1A Auto

It would be best to just replace the sensor.

 

Check the wiring in the harness from the connector behind the wheel hub backwards to the main harness as far as you can......often just a frayed or damaged wire, IMO.....not too tough a repair if that's what it is.....
