how does a tps sensor work

A TPS (throttle position sensor) is a crucial component in a vehicle's fuel management system. It works by monitoring the position of the throttle valve and sending this information to the engine control unit (ECU). The ECU uses this data to calculate the amount of air entering the engine, allowing for precise fuel injection and optimal engine performance. This sensor is typically located on the throttle body and consists of a potentiometer that measures the angle of the throttle valve. As the throttle valve opens or closes, the sensor adjusts its output voltage accordingly. This data is then used by the ECU to make adjustments to fuel delivery, ignition timing, and other engine parameters in real time. An accurate and functioning TPS is essential for efficient fuel consumption, smooth engine performance, and reduced emissions. It is a critical component in modern engine management systems, ensuring optimal power output and vehicle drivability.
