Code C1416 Lexus Description

The speed sensor detects the wheel speed and sends the appropriate signals to the Skid Control ECU (Brake Actuator Assembly). These signals are used for Anti-Lock Brake System (ABS) control. Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change when the rotors turn. Each speed sensor detects that magnetic change and sends a pulse signal to the Skid Control ECU (Brake Actuator Assembly).
