Right Rear Speed Sensor Circuit

DTC 33 RIGHT REAR SPEED SENSOR CIRCUIT

CIRCUIT DESCRIPTION

DTC Detection Condition:

The speed sensor detects wheel speed and transmits the appropriate signals to the ECU. These signals are used for control of the ABS and VSC control systems.

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:
- DTCs No. C0210/33 and C1238/38 are for the right rear speed sensor.
- DTCs No. C0215/34 and C1239/39 are for the left rear speed sensor.
