Sensor RH 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.
HINT
- DTC C1403 is for the rear speed sensor RH.
- DTC C1404 is for the rear speed sensor LH.
