Throttle Position Sensor

The Throttle Position Sensor (TPS) is a component that is part of the supply class Miscellaneous Engine Accessories, Nonaircraft in the supply group Engine Accessories.

The TPS is an electronic sensor that is typically located on the throttle body of an engine. Its main function is to monitor the position of the throttle plate or butterfly valve, which controls the amount of air entering the engine. The TPS sends this information to the engine control unit (ECU), allowing it to adjust the fuel injection and ignition timing accordingly.

By monitoring the throttle position, the TPS helps optimize engine performance, fuel efficiency, and emissions. It also plays a crucial role in various engine control systems, such as electronic throttle control (ETC) and cruise control.

Overall, the Throttle Position Sensor is an important component in the engine system, ensuring proper engine operation and performance.
