A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used. For example, an extra "closed throttle position sensor" (CTPS) may be employed to indicate that the throttle is completely closed. Some engine control units (ECUs) also control the throttle position by electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control.[1]

Related to the TPS are accelerator pedal sensors, which often include a wide-open throttle (WOT) sensor. The accelerator pedal sensors are used in electronic throttle control or "drive by wire" systems, and the most common use of a wide-open throttle sensor is for the kick-down function on automatic transmissions.

Modern-day sensors are non-contact type. These modern non-contact TPS include Hall effect sensors, inductive sensors, magneto resistive and others. In the potentiometric type sensors, a multi-finger metal brush/rake is in contact with a resistive strip,[2] while the butterfly valve is turned from the lower mechanical stop (minimum air position) to WOT, there is a change in the resistance and this change in resistance is given as the input to the ECU.
