If the ABS wheel speed sensor was faulty, once the new hub/sensor is installed, and you drive the vehicle, the warning lights should go out. To determine what is going on, you can manually erase the trouble codes using an appropriate scan tool and if the warning lights stay off, then the problem is resolved. If the lights return, either the wheel speed sensor was not faulty (not an unusual scenario as the output of the sensor has to be directly tested to determine if the sensor is faulty versus a circumstance where there is just a loose connection in the circuit to and from the sensor; trouble codes can NOT be the sole basis to condemn the sensor; it must be tested) or there is more than one cause of the fault. If you are seeking a resolution to this, and you want a professional mechanic to conclude this, please request a warning light diagnostic and the responding certified mechanic will get this resolved at the lowest possible cost, right at your location.
