c0045 & c0050 wont go away

I have an issue where I have the codes c0045 and c0050, which is both rear speed sensors and cannot get rid of them at all. I have had both rear wheel bearings replaced as well as the rear abs harness and the recall has been done as well. The lights on the dash are traction control, abs and brake light as well which everybody I talked to told me it would surely be a wheel bearing. All the plugs look good and not corroded. I've cleaned every plug with electronic cleaner also. Anyone have any ideas ? Thank you

Just fixed this. Problem was a broken wire under the car. Under the passenger side just about where the back seat is there is a connector. The connector is about a foot inside. Check both sides of the plug for broken wires. If I remember correctly the brown and green wires are the hot ones and should have close to battery voltage.
