Vehicle Speed Sensor Signal Buffer: Description and Operation
The
Vehicle Speed Sensor (VSS) buffer receives a signal from the VSS (permanent magnet generator) indicating vehicle speed.
The buffer processes the signal which is then sent to the
Engine Control Module (ECM), cruise control module and speedometer.
