Vehicle Speed Sensor: Description and Operation
Output Shaft Speed (OSS) Sensor
OUTPUT SHAFT SPEED (OSS) SENSOR
The OSS sensor provides the PCM with information about the rotational speed of an output shaft. The PCM uses the information to control and diagnose
powertrain behavior. In some applications, the sensor is also used as the source of vehicle speed. The sensor may be physically located in different places
on the vehicle, depending upon the specific application. The design of each speed sensor is unique and depends on which powertrain control feature uses
the information that is generated.
