Front Speed Sensor RH Circuit

DTC C0200/31 Front Speed Sensor RH Circuit

DESCRIPTION

DTC Detection Condition:

The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used to control the ABS, BA, TRAC, A-TRAC, VSC, downhill assist control and hill-start assist control control systems. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing.

To detect the rotation direction, the output waves are used to determine the relationship of the pulses that are generated by 2 MREs. Upon receiving this signal, the sensor IC outputs a forward or backward wave to the skid control ECU.

HINT:
- DTC C0200/31 and C1235/35 are for the right front speed sensor.
- DTC C0205/32 and C1236/36 are for the left front speed sensor.
