Output Shaft Speed (OSS) Sensor
The OSS sensor measures the speed of the output shaft. The rotation direction is not measured.
The OSS sensor is located in the clutch housing above the differential.
The OSS sensor is an inductive sensor which detects the vehicle speed by means of an impulse ring on the differential.
The signal is used for the following functions among other things:
- to determine the shift timing.
- to supply the vehicle speed input signal for the TCM.
