Turbine Shaft Speed Sensor
WARNING: This page is about a different car, the 2002 Ford Escape, 2001 Mazda Tribute, and 2001 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The Turbine Shaft Speed Sensor (TSS) sensor is a magnetic pick-up that sends turbine shaft speed signal to PCM. The TSS sensor provides converter turbine speed information for Torque Converter Clutch (TCC) strategy, which is also used in determining static EPC pressure settings. Malfunction of sensor may cause harsh engagements of shifts. Lack of 4th gear or no engine braking in manual 2nd or manual 3rd gear may also result.
