Vehicle Speed Sensor: Description and Operation

Vehicle Speed Sensor

The vehicle speed sensor consisting of the reed switch and magnet is built in the speedometer. As the magnet turns with the speedometer cable, its
magnetic force causes the reed switch to turn "ON" and "OFF." Such "ON/OFF" frequency increases or decreases in proportion with the car speed and is
sent to the ECM as pulse signals.
