P1901 Ford Code - Turbine Shaft Speed Sensor Circuit Intermittent
Quick Answer
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. Common causes include Turbine Shaft Speed (TSS) sensor not installed correctly, Faulty Turbine Shaft Speed sensor, Turbine Shaft Speed sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
