Circuit Description
WARNING: This page is about a different car, the 2005 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used for control of the ABS & BA & TRAC & VSC control 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 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.
