The throttle position sensor, sometimes known as a TPS, is an electrical device designed to monitor the position of the vehicle throttle valve, plate, butterfly or spindle. The throttle position sensor is an integral part of the vehicle engine management system, located in or on the throttle body assembly; the throttle position sensor enables the vehicle engine management system (ECU) to accurately determine the angle and rotational speed of the vehicle throttle valve. The throttle position sensor output signal is used by the ECU to identify throttle position required for fuel and air delivery, ignition timing and other important functions. The throttle position sensor must be compatible with the vehicle engine management system; the Tridon throttle position sensor range has been carefully researched and engineered to suit each specific application.
