Anh Tuan, a seasoned truck driver from Gia Lam district, Hanoi, once faced a frustrating issue with his truck overheating. Every trip from Gia Lam to Lang Son resulted in high-temperature warnings, forcing him to stop frequently. He tried everything from changing the coolant to checking the radiator, but the problem persisted. Finally, after seeking help from a mechanic friend on Le Duan street, he discovered the culprit: a faulty engine temperature sensor.

Anh Tuan’s experience highlights the crucial role of the temperature sensor – a small but vital component in a truck’s cooling system, especially for vehicles carrying heavy loads and traveling long distances.

What is an Engine Temperature Sensor?

An engine temperature sensor, also known as the Engine Coolant Temperature (ECT) sensor, is a small electronic device that monitors the engine’s temperature and sends this information to the Engine Control Unit (ECU). The ECU uses this data to adjust the fuel injection and ignition timing, ensuring the engine operates at its optimal temperature.

The Vital Role of the Engine Temperature Sensor

Don’t let its small size deceive you! This component plays a critical role in maintaining the health of your truck’s engine:

Engine Temperature Control: Excessively high or low engine temperatures negatively impact performance and engine lifespan. The temperature sensor enables the ECU to maintain the ideal temperature range, preventing overheating or excessive cooling.
Engine Performance Optimization: When the engine operates at the optimal temperature, fuel combustion is more efficient, leading to improved power and fuel economy.
Emission Reduction: Effective temperature control contributes to reducing harmful emissions, promoting a cleaner environment.

Engine Temperature Sensor Price List

The price of an engine temperature sensor varies depending on the vehicle model, manufacturer, and supplier. Below is a reference price list:

Vehicle Type	Manufacturer	Estimated Price (VNĐ)
Hyundai Truck	Hyundai	500,000 – 800,000
Hino Truck	Hino	700,000 – 1,200,000
