Output Shaft Speed (OSS) Sensor

The OSS  sensor is a Hall-effect type sensor that provides a signal to the PCM that changes in frequency as the rotating speed of the output shaft ring gear varies.

The PCM also compares the OSS  sensor signal with the TSS  sensor signal to determine the gear ratio provided by the rear planetary gearset.

The PCM uses the OSS  sensor signal as an input for its strategies for shifts and TCC  operation. The PCM also uses the OSS  sensor signal for transmission fault detection and diagnostics.

Refer to the component illustration in Molded Leadframe  for the location of the OSS  sensor.
