· The coolant temperature sensor monitors and measures the engine’s coolant or antifreeze’s temperature with electrical resistance – which the sensors use to operate. This indicates how much heat the engine is giving off. Its job is to ensure that the engine is running at its optimum temperature. The coolant temperature sensor …
· The coolant temperature sensor is comprised of a metal housing filled with a composite which varies the resistance through its internal circuit as the engine temperature increases or decreases. When there is a coolant leak or the engine has a blown head gasket the sensor can be fooled because of the air or exhaust trapped in the cooling system which the sensor …
The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature. The onboard computer uses the signal of ECT as the main correction factor when calculating the ignition advance and the injection duration. Appearance The ECT sensor is shown on fig. 1. Fig. 1 ...
Coolant temperature sensors are used by the fuel management system to detect the engine's operating temperature. Depending on the sensor information, the control unit adapts the injection time and firing angle to the operating conditions. The sensor is a temperature sensor with a negative temperature coefficient. This means that the internal resistance reduces as the temperature increases.

The coolant temperature sensor is a crucial component for ensuring your engine performs at an optimal level. It is based on the signals from the sensor that the car computer calculates engine timing and fuel injection. If the signal is wrong, this important calculation will be misjudged. If you notice any of the above signs, have your car checked immediately to avoid potential engine trouble ...
· The engine coolant temperature (ECT) sensor is one of the most important; engine management sensors. Because, its readings play a key role in calculations, which affect engine performance. As a result, the (ECU) uses this data to adjust the, fuel injection and ignition timing. Engines require more fuel when they are cold.
· The coolant temperature sensor can also fail in such a way that it sends an always-hot signal. This can cause the computer to compensate for a lean signal incorrectly, resulting in overheating, misfires, and even engine ping. Check Engine Light comes on . Another sign of a problem with the coolant temperature sensor is an illuminated Check Engine Light. If the computer detects a problem …

The coolant temperature sensor is fastened to the intake manifold of an engine coolant and is often referred to as a negative temperature coefficient type of sensor. In terms of resistance capacity, this coolant sensor has 20,000 ohms at 248 degrees Fahrenheit. There is an inverse relationship between the electrical resistance and the engine coolant ( when the engine coolant temperature ...
· Once the coolant temperature sensor has been replaced, you need to start the engine, check for leaks, and refill the radiator fluid in most cases before you test drive the vehicle. The best way to complete any road test is to have a planned route that will bring your engine to proper operating temperature and open the thermostat of your radiator. Step 1: Start the vehicle. Let it warm up to ...
· The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling …
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. From there, your vehicle’s computer will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature …
The coolant temperature sensor has a built-in NTC resistor. The resistance of a Negative Temperature Coefficient (NTC) resistor decreases when the temperature increases. The resistor in the sensor together with a resistor in the ECU forms a voltage divider which is fed by a 5 V power supply. If the temperature changes, the resistance and the signal voltage at the dividers output changes. The ...
