Toyota Camry (XV70): Right Front Wheel Speed Sensor Circuit Short to Battery (C050612)
DESCRIPTION
Each speed sensor detects wheel speed and sends signals to the skid control ECU (brake actuator assembly). These signals are used by the ABS control.
The speed sensor detects the magnetic fields of the speed sensor rotor as it rotates and outputs a pulse signal.
The frequency of the pulse varies in accordance with the rotational speed of the speed sensor rotor and the system uses this to determine the wheel speed.
