VehiCROSS 4WD V6-3.5L (1999)
Vehicle Speed Sensor: Description and Operation
The PCM determines the speed of the vehicle by converting a plusing voltage signal from the vehicle speed sensor (VSS) into miles per hour. The PCM
uses this signal to operate the cruise control, speedometer, and the TCC and shift solenoids in the transmission. For more information on the TCC and
shift solenoids, refer to Automatic Transmission.
With the starter switch in ON or START, the VSS receives power. For every rotation, the VSS outputs four pulses to the cruise control unit, powertrain
control module (PCM), and the speedometer to gauge speed.
