Turbine Shaft Speed (TSS) Sensor
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The turbine shaft speed (TSS) sensor is a magnetic pickup that sends the PCM torque converter turbine speed information.
The TSS sensor is mounted externally on the case.
The PCM uses TSS information to help determine appropriate operating pressures and TCC operation.
