DTC C1415: Rear Speed Sensor RH Output Malfunction; DTC C1416: Rear Speed Sensor LH Output Malfunction: Description

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for 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.
