The codes are for the rear wheel speed sensors, right and left. Since it is giving the codes for both sensors you will need to check the wiring from each sensor. The best option will be to unplug the sensors wiring at each connector then clean the connector pins and inspect the wiring insulation. Then reconnect the sensors and clear the codes.
