The Crucial Role of the Throttle Position Sensor in Your Vehicle

Anh Tuan, owner of a Hyundai H100 truck used for hauling goods in the Cau Giay district of Hanoi, had a terrifying experience when his truck suddenly stalled in the middle of busy Truong Chinh Street. The culprit? A faulty throttle position sensor that prevented him from accelerating. Fortunately, a friend recommended a reputable auto repair shop nearby, where Anh Tuan quickly had the sensor replaced and was back on the road. This incident solidified his understanding of the vital role the throttle position sensor plays in vehicle safety and performance.

What is a Throttle Position Sensor?

The throttle position sensor (TPS) is a critical electronic component in a vehicle’s fuel injection system. It measures the angle of the throttle plate and converts it into a voltage signal, which is then sent to the engine control unit (ECU). The ECU uses this signal to precisely calculate and adjust the amount of fuel injected into the engine, ensuring smooth operation and fuel efficiency.

Functions of the Throttle Position Sensor

• Controls Fuel Injection: The TPS helps the ECU determine the necessary fuel amount based on the driver’s accelerator pedal position.
• Facilitates Easy Starting: During a cold start, the TPS signals the ECU to increase fuel injection, making it easier for the engine to start.
• Maintains Stable Engine Speed: The TPS helps maintain a steady engine speed at idle or low speeds.
• Improves Fuel Economy: By providing precise fuel delivery, the TPS contributes to more efficient engine operation and better fuel economy.
