Vehicle Speed Sensor: Description and Operation
Vehicle Speed Sensor
The Vehicle Speed Sensor (VSS) is mounted on the front of the rear axle housing above the pinion flange. The speed sensor ring is located in the rear
axle between the ring gear and differential case. The signal from the sensor is not routed directly to the Powertrain Control Module (PCM). It is received
by the Programmable Speedometer/Odometer Module (PSOM), which provides the PCM with a vehicle speed signal.
