Code C1333 Scion Description

Each speed sensor detects wheel speed and sends the appropriate signals to the Skid Control ECU. These signals are used by the ABS control system. The speed sensor rotors have rows of alternating N and S magnetic poles. Hall IC type speed sensors use the frequency of output pulses to detect the vehicle speed. Because the sensor outputs digital pulses, it can detect the vehicle speed even when the vehicle is nearly stationary.
