THROTTLE POSITION SENSOR (TPS)

\

General description

      A throttle position sensor (TPS) is used to monitor the throttle valve position in internal combustion engines. TPS is usually located on the throttle valve spindle so that it can directly monitor its position.
      The TPS sensor is a potentiometer, providing a variable resistance depending on the position of the throttle valve (and hence throttle position sensor).
      The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending on the position of the throttle valve, and also depending on the rate of change of that position.
      Some throttle valve modifications have built-in end switches. They are closed throttle position sensor (CTPS) and often include a wide open throttle (WOT) sensor which is mounted on the accelerator pedal.
      Throttle position signal can be produced from a simple contact (TS) or a potentiometer (TPS), and also of combined TS/TPS sensor. Some systems use both types as separate elements.
