Vehicle Speed Sensor/Transducer - Cruise Control: Description and Operation

The Vehicle Speed Sensor (VSS) is mounted to the automatic transaxle and provides a low voltage Alternating Current (AC) signal to the Powertrain
Control Module (PCM). The PCM converts the AC signal to a pulse width modulated Direct Current (DC) signal, which is sent to the cruise control
module at a rate of 4000 pulses per mile.
