how does tps sensor work

The TPS (Throttle Position Sensor) is a crucial component in modern fuel-injected engines, providing valuable data to the engine control unit (ECU). The TPS sensor works by monitoring the position of the throttle valve and sending this information to the ECU, allowing it to determine the appropriate air-fuel mixture for optimal engine performance and efficiency. The TPS sensor utilizes a variable resistor or a potentiometer to measure the angle of the throttle valve. As the throttle is opened or closed, the resistance of the sensor changes, and this change in resistance is converted into a voltage signal that is then relayed to the ECU. The ECU uses this data to make real-time adjustments to the fuel injection and ignition timing, ensuring smooth engine operation and efficient power delivery. Overall, the TPS sensor plays a critical role in maintaining the balance between engine power and fuel consumption, making it an essential component in modern engine management systems.
