C1277 TOYOTA Description
The speed sensor detects the wheel speed and sends the appropriate signals to the Skid Control ECU. These signals are used for brake control. The 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.
