Recently I have been having the ABS and traction control light coming on. It will come on for awhile and then will stay off the next time I start my car. Its popped on probably about 4 times in the last week. I took it by Autozone so they could hook up their computer to find out specifics and this is what popped up.

right rear wheel speed sensor circuit b0050

Does anyone have any information on what that means and how serious it is?
Thanks in advance!

I encourage you to take the vehicle in for an inspection. If a sensor is not operating correctly, it may affect the ABS and TCS. After an inspection, a certified technician will be able to offer additional information.
