OPERATION
The vehicle speed sensor, which is located in the speedometer, converts the vehicle speed into a pulse signal and inputs it to the engine control module, which then provides the idle air control, etc., based on this signal.
The vehicle speed sensor generates the vehicle speed signal by repeatedly opening and closing between the voltage of about 5V applied from the engine control module and ground using a reed switch.
