Question

Quizplus · Accepted Answer

Technician A is correct because magnetic wheel speed sensors use a magnetic field to detect wheel speed, while the toothed sensor ring, also known as a tone wheel, is typically made of metal and is not magnetic itself; it serves as a target for the magnetic sensor.
