Hello. Welcome to Just Answer. Please allow me to assist you. Unfortunately, the sensors cannot be tested with only an ohm meter. You can read a resistance value form the sensor, but, that only tells you the windings that surround the magnet are good. In order to properly test a sensor like this, you need access to an oscilloscope, or a scan tool that is high enough in capability to 'read' the indivual wheel speed sensors in real time. Not all scanners do this. Of course, the Toyota scan tool at a Toyota dealer service department will read all 4 wheel speed sensors. If you do not have an oscilloscope, and you want an accurate diagnosis, the Toyota svc dept is your best bet. Normal causes of sensor failure are people beating on the hubs to remove the wheel bearings, excess rust particle buildup whre the sensor resides, broken or misplaced sensor during reassembly, or the toothed gear that the sensor 'reads' is damaged. If the ABS/VSC/Trac lights are on after a wheel bearing replacement, and it was not on when you took it in, they broke something or did something to cause the problem.
