Wheel speed sensor issue
 

Hey guys. Been having my ABS and TCS lights on the dash stay on (not on/off based on brake usage like some people have posted) and after a few minutes of driving the TPMS begins to flash, even though the tires all have air in them. I already checked all my fuses, verified all my brake lights work and my AccessPort is saying I have a bad wheel speed sensor on the back right wheel. I went under my car just now to check out the cable and it looks perfectly fine and is plugged in tight.

My question is based on what I've read am I really going to have to buy a completely new wheel hub to replace this sensor? If so can anyone point me in the right direction to order one?
