The Wheel Speed Sensors (WSS) receive an ignition voltage from the EBCM (Electronic Brake Control Module). On the other hand, they deliver a DC square wave signal to the module. As the wheel rotates, the signal produced by the sensor is used by the EBCM to calculate the wheel speed.
A Wheel Speed Sensor is defined as a hall effect type sensor, which is equipped with a reluctor wheel or ring. As the ring moves, the teeth of the ring interrupt the magnetic field, creating pulses that are sent to the control module. These pulses are interpreted as speed.
When the DTC C0035 OBDII code is set, it is because the Left Front Wheel Sensor malfunctioned. The reason is that the actual operating values do not match those set by the manufacturer.
