Throttle Position Sensor (TPS)

Throttle Position Sensor (TPS)

An essential part of the electronic throttle control system, the Throttle Position Sensor (TPS) keeps track of the angle of the throttle valve in a car. The throttle body houses a butterfly valve that regulates the engine’s power by regulating the amount of air entering it. It is situated between the air cleaner and the engine’s intake manifold.


The TPS functions as a potentiometer, offering changing resistance based on the angle at which the throttle valve opens. The TPS transmits an output voltage of roughly 4.5 volts to the Engine Control Unit (ECU) when the throttle valve is fully open. This data is processed by the ECU along with information from other sensors, such as the Mass Air Flow Sensor, to establish the ideal air-fuel ratio and ignition timing, enabling exact modifications for optimal engine performance.


The Hall Effect may occasionally be used by the TPS in place of a potentiometer. The Hall Effect is dependent on magnetic fields that alter as the throttle opens and closes in order to gather the necessary data.


Rotating position sensors, thick film PCB resistors, and resistive film sensors are just a few of the TPS Microelectronics’ specialty products.
