Steering wheel angle
sensor connector
Steering wheel angle sensor
The steering wheel angle sensor is integrated with the phototransistor and the LED and there is a slotted plate
between them. When the inner slotted plate rotates with the steering column shaft when the steering wheel is
turned, the voltage occurs through the holes. The detected voltage will be transmitted to the ECS unit as a pulse
from the 3 terminals. Then, the two voltage pulses are used to get the average value for detecting the steering wheel
position and its angle speed. And the other pulse is used for checking the alignment of the steering wheel.
