WebbA throttle position sensor signals the position of the throttle valve to the Engine Control Module (ECM). Throttle potentiometers are generally carbon track type units mounted directly onto the throttle butterfly spindle. They are a three-wire device with a reference 5 V supply, output signal and earth terminals. WebbTPS 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.
