2011 Santa Fe, Tested and and replaced the wheel speed sensor. That was not the problem. Took it to the dealer and they said it was the wiring harness and would cost $4500.00. I said that’s not going to happen. Took it home and tested some wires. All wires have continuity, they did say that the Ohms resistance was too high so their must have been a break of some wires. So I replaced the 2 wires coming from right front speed sensor to the ECM by cutting the the wires next to the connectors and soldering new ones on, a $4 fix.
