What is an Engine Coolant Temperature Sensor in a car? Where is it installed? I believe that many car enthusiasts have not even heard of this part. Today I will talk to you about this sensor!
What is the coolant temperature sensor?
It is a sensor used to check the working condition of the engine cooling system. It measures the temperature of the coolant in real-time and transmits this information to the engine control unit, helping to adjust the engine so that it is always in optimal working condition.
In fact, the coolant temperature sensor is particularly important, because the car is indispensable for cooling, now in the summer, the transmitter speed a high temperature soared, if there is no cooling, this tank is an immediate scrap, which reflects the role of the coolant sensor.
Automobile coolant temperature sensor location
The CTS sensor is generally installed in the engine block or cylinder head on the reservoir water jacket, and coolant direct contact is used to measure the coolant temperature of the automobile engine, and the temperature sensor is actually using a negative temperature coefficient thermistor, the resistance value of the resistance will be lowered as the temperature rises when it falls to a certain level when the alarm will be issued.
The role of the coolant temperature sensor
1. detection of water temperature:
2. prompt the owner, and prevent failure:
Although the sensor is installed in the engine, in the instrumentation system on the design of the coolant temperature table, you can use the CTS sensor to detect the engine coolant temperature, and then display it on the dashboard, so that drivers can intuitively see it that the engine coolant temperature in any working conditions, and make timely and appropriate treatment, and in the case of high temperature will be alarmed! Tips to prevent the automobile water tank boil.

Thank you for your question.
An Engine Coolant Temperature Sensor (ECT Sensor) is a key component of the engine management system. It measures the temperature of the engine’s coolant and sends this data to the ECU (Engine Control Unit).
With this information, the ECU can:
Adjust the fuel injection and ignition timing
Optimize engine performance and fuel efficiency
Control the operation of the cooling fan
Prevent engine overheating
A faulty ECT sensor may cause poor fuel economy, starting issues, or overheating problems.
At LOREADA, we specialize in high-quality engine sensors, including ECT sensors, MAP sensors, MAF sensors, and throttle body assemblies. All our products are designed for reliability and long service life.
