Right Front Speed Sensor

DTC 31 RIGHT FRONT SPEED SENSOR

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used to control the ABS control system. The front and rear rotors have 48 serrations, respectively.

When the rotors rotate, the magnetic field emitted by the permanent magnet in the speed sensor generates 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:
- DTC Nos. C0200/31 and C1235/35 are for the right front speed sensor.
- DTC Nos. C0205/32 and C1236/36 are for the left front speed sensor.
