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 skid control ECU. These signals are used for the ABS control system. 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 ECU.

DTCs C1271/71 and C1272/72 can be deleted when the speed sensor sends a vehicle speed signal or the Test Mode ends. DTCs C1271/71 and C1272/72 are output only in the Test Mode.

HINT:
- DTC C0200/31 is for the front speed sensor RH.
- DTC C0205/32 is for the front speed sensor LH.
