Vehicle Speed Sensor: Description and Operation
Vehicle Speed Sensor (VSS):
The
Vehicle Speed Sensor (VSS) is located near the output shaft of the transmission (2WD) or the transfer case (4WD). The VSS contains a driven gear that triggers a hall switch. The PCM receives a voltage signal from the VSS and uses the signal to help control transmission and engine operation.
