Trooper LS V6-3.5L (1998)
Vehicle Speed Sensor: Description and Operation
General Description
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 4L30-E Automatic Transmission.
