Many discussion about rotor, sensor rotor, sensor signal, rear speed sensor, brake, right rear speed, connector, left front speed, speed sensor circuit, sensor connector check, installation, and terminals are described in this technical information. The technical information gives the reader discussion such as circuit, disconnect speed sensor, rear, right front speed, vehicle speed, signal waveform, speed sensor preparation, left rear speed, sensor circuit, check speed, rotor preparation, and serrations.
Inside the technical information you can read explanation like resistance, missing teeth check, signal, rear speed, preparation, right front, system, wheel speed, speed, speed sensor, system check, and anti–lock brake system. Here are taken from this technical information:
he speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used to control the ABS system. The front and rear rotors each have 48 serrations. When the rotors rotate, the magnetic field emitted by the permanent magnet in the speed sensor generates an AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.
