Output Shaft Speed Sensor

Output Shaft Speed (OSS) sensor provides PCM with information about rotational speed of transmission output shaft. PCM uses information to control and diagnose powertrain behavior. In some applications, OSS sensor is also used as source of monitoring vehicle speed. OSS sensor may be physically located in different places on vehicle, depending upon the specific application. Design of each OSS sensor is unique and depends on which powertrain control feature uses the information generated.
