Signal from sensor

The sensor is supplied power from pin 1 and ground on pin 2 of the EHPS control module. Pin 3 provides information on steering speed via a 500 Hz PWM signal. The pulse ratio carries information on steering speed - 12.5% to 87.5%, which corresponds to 0 degrees/second to 60 degrees/second.
