Vehicle Speed Sensor: Description and Operation
This sensor, located on the backside of the speedometer cluster, is used to monitor actual vehicle speed. Vehicle speed information is used by the ECU for fuel injection, air injection (on equipped vehicles), cruise control and electronic control of automatic transmissions. The
VSS inputs the ECU through terminal SPD.
