DTC C0200/31 Front Speed Sensor RH Circuit

DTC C0205/32 Front Speed Sensor LH Circuit

DTC C1271/71 Low Output Signal of Front Speed Sensor RH (Test Mode DTC)

DTC C1272/72 Low Output Signal of Front Speed Sensor LH (Test Mode DTC)


DESCRIPTION

The speed sensors detect wheel speed and transmit the signals to the ECU. These signals are used for control of the ABS control system. Each of the front and rear rotors have 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.
DTCs C1271/71 and C1272/72 can be deleted when the speed sensor sends a wheel speed signal or the Test Mode ends. DTCs C1271/71 and C1272/72 are output only in the Test Mode.

9.CHECK SPEED SENSOR AND SPEED SENSOR ROTOR SERRATIONS


    Camry. Acv40 Gsv40.Brake Control.Anti-Lock Brake System. Dtc C0200/31 Front Speed Sensor Rh Circuit

  1. Reconnect the front speed sensor connector.

    OK:
    The same waveform is output from all the 4 wheels and there is no noise or interference in the waveform.
    HINT:
    1. As the vehicle speed (wheel revolution speed) increases, a cycle of the waveform narrows and the output voltage becomes greater.
    2. When noise is identified in the waveform on the oscilloscope, the erratic signals are generated due to speed sensor rotor's scratches, looseness or foreign matter attached to it.
