ABS Warning Light Due to Failed Wheel Speed Sensor on Toyota Camry

Problem Description and Possible Solution

At higher mileages, an anti-lock brake system wheel speed sensor may wear out and illuminate the ABS warning light. It is recommended to replace the sensor with a factory part and be sure to clean all rust and debris from the mounting area because the mounting distance is critical. Failure to do so may result in the new sensor setting false trouble codes. Be sure to check the condition and runout of the front wheel bearings on the 2WD and 4WD vehicles and the CV joints on the 4WD vehicles since worn wheel bearings and/or CV joints can cause the ABS trigger rings to rub against the ABS sensors and damage them.

Recently purchased used for a work car. The ABS light stays on but the car handles and breaks perfectly. The guy I bought it from stated that it was a bad sensor but couldn't remember exactly which one. I'll replace it based upon this blog and let you know what happens...
ABS/Brake light come on at same time intermittently. Told it was a bad sensor and not to worry about it by two different mechanics.
ABS light comes on; I had the front and rear brakes replaced; struts replace; fuel ingition cleaning, power steering pressure line replace; 3 speed sensors right side replaced and I am going back to probably get my 4th speed sensor tomorrow.
ABS light comes on intermittently. Checked code and found it to be right front wheel sensor. Removed sensor and found metal shavings attached to the sensor. Looked into sensor mounting hole and saw evidence of the exciter ring striking the sensor. No indication of bad wheel bearing or CV joint. Replaced wheel bearing and drive axle and cleaned sensor. Problem has not returned.
It not fix yet. The brake and abs light is on and the odometer don't work. Sometime it will come on and go off
