CIRCUIT DESCRIPTION
The speed sensor consists of the reed switch and magnet. It 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 vehicle speed and is sent to ECM (PCM) as pulse signals.

ECM (PCM) uses it as one of the signals to control various devices.
