Output Shaft Speed (OSS) Sensor

The OSS sensor is a magnetic pick-up. It sends a voltage signal to the PCM. This signal tells the PCM transmission output shaft speed RPM. The signal is also used for shift schedules, modulated converter clutch control, and determining EPC pressure.

OSS is located on the rear of transmission case on driver's side of vehicle. Control functions associated with OSS are limiting vehicle speed, converter clutch control and shift quality.
