Turbine Shaft Speed (TSS) Sensor and Primary Variator Speed Sensor
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The primary variator speed sensor and the turbine shaft speed (TSS) sensor are housed in the transmission control module (TCM). The TCM is attached to the mechatronic unit. Both speed sensors are Hall-effect.
The primary variator speed sensor reads the primary pulley shaft speed.
The speed sensor for the primary pulley is part of the transmission control module. It is an non-contact Hall sensor which measures the rotational speed of the primary pulley.
