Pinpoint Test K : TSS (Turbine Shaft Speed) Sensor: Notes
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
TSS Sensor
Refer to Transmission Controls - 6F50/6F55 for schematic and connector information.
Normal Operation
The TSS sensor is a Hall-effect sensor that sends a signal to the PCM that indicates transmission turbine shaft input speed. The TSS sensor provides converter turbine speed information for TCC strategy.
