Grand Prix V6-3100 3.1L VIN M SFI (1996)
Vehicle Speed Sensor: Description and Operation
DESCRIPTION
The Vehicle Speed Sensor (VSS) sends a pulsing voltage signal to the PCM which the PCM converts to miles per hour. This sensor mainly
controls the operation of the TCC, shift solenoids, and cruise control systems. There are several different types of vehicle speed sensors. A scan
tool display should closely match with speedometer reading with drive wheels turning.
