2016 Sante Fe Sport .ABS light, traction control light, car on incline triangle light all on at once. Plugged up at Auto Zone, shows two codes: C1209 Wheel Speed Sensor Rear-RH Open/Short. C1210 Wheel Speed Sensor Rear -RH Range /Performance / intermittent . I disassembled the right rear wheel, only wiring harness attached is a two pronged plugged connector. Looks like new, all clean. Anyone have this problem before? No local parts vendors stock this harness, some can't even order it. Some say the ABS sensor and wheel speed sensor are two seperate items: Might be true, but there is only one harness attached to the right rear assembly. I've got a feeling this isn't the issue. Any help would be appreciated. Thanks

 

One way to handle this problem is;
Have a capable scan tool graph what is happening so we know just where to go.The graph will tell us if the signal is dropping out, is insufficient or is just not there at all.
Without that guidance, we can just keep replacing stuff and hoping we find and hit the cause.
There are limits as to what diagnosing we can do these days without the proper equip.
If you have the time and $$$ to keep guessing it will probably cost more to do that than have a good shop troubleshoot the root cause.
