Output Shaft Speed (OSS) Sensor

WARNING: This page is about a different car, the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, and 2016 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.

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

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

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