I'd say (A) Technician A


Wheel speed sensors are a necessary sensor input and ABS component. The conventional wheel speed sensor consists of a magnetic pin with copper wire wrapped around to create a magnetic field. The purpose of the toothed metal ring is to pass through the sensor’s magnetic field. The sensor changes polarity as the metal ring passes through.
