The vehicle speed sensor (VSS) is mounted to the automatic transaxle. The VSS 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. The signal is sent to the cruise control module at a rate of 4,000 pulses per mile.
