The fronts particularly move with the wheel and the cable is liable to crack. I keep a can of marine "liquid rubber" around to teat ABS sensor wiring. Sensor should be in the $60-$90 range.
Am not surprised that the error codes might be less than accurate, if a wheel sensor is indicated, first thing I do is to raise the car, remove the wheels, and check for a cracked, frayed, or twisted sensor lead. The defect is usually quite visible.
