Toyota Corolla Repair Manual: Circuit description

The speed sensor detects wheel speed and transmits the appropriate

The speed sensor detects wheel speed and transmits the appropriate signals to the ecu. These signals are used for control of the abs control system. Each of the front and rear rotors has 48 serrations.

When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces 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.

Hint:

Hint

: Dtc no. C0200/31 and c1235/35 is the right front speed sensor.

Dtc no. C0205/32 and c1236/36 is the left front speed sensor.
