P1901 MAZDA Description
The Turbine Shaft Speed (TSS) sensor is a Hall-effect pickup that sends a signal to the Powertrain Control Module (PCM) or Transmission Control Module (TCM) that indicates transaxle turbine shaft input speed. The TSS sensor provides converter turbine speed information for the Torque Converter Clutch strategy. Also used in determining static Line Pressure Control (LPC) pressure settings. The Diagnostic Trouble Code (DTC) will set when the TSS sensor signal to the PCM is irregular or interrupted.
