With the development of high and new technology, the various types of equipment of automobiles have been continuously improved to meet the ever-increasing needs of people. The new energy vehicle temperature sensor can effectively monitor the temperature of the car, help people detect the safety of the car during the driving process, and protect the safety of the people in the car to the greatest extent. In modern society, the temperature sensor of new energy vehicles has become an indispensable device for people.

Do you know the working mechanism of the intake air temperature sensor of the new energy vehicle temperature sensor?

How to check the intake air temperature sensor in the new energy vehicle temperature sensor?

What are the links to check the resistance of the new energy vehicle temperature sensor and the ECU connection line?

Do you know the working mechanism of the intake air temperature sensor of the new energy vehicle temperature sensor?

It mainly detects the temperature of the air penetrating the air duct and inputs the intake air temperature signal to the EUC as fuel injection and ignition timing correction signal. Mainly installed on the intake hose of the air cleaner and the airflow sensor.

This sensor can also be called a water temperature sensor. Its main function is to detect the temperature of the engine coolant and input a temperature signal to the ECU as a correction signal for the injection and ignition timing. The sensor is generally installed on the cylinder water channel and the cylinder head water channel. , The upper outlet pipe, etc., is in contact with the coolant. Inside it is a semiconductor thermistor with a negative temperature coefficient NTC.

How to check the intake air temperature sensor in the new energy vehicle temperature sensor?

The air intake temperature sensor ground wire is not in good contact, the data stream will show abnormal low temperature, and the low-temperature air density is high, which will increase the fuel injection pulse width and cause the mixed steam to be too thick. If the sensor is short-circuited, the data stream will show abnormally high temperature, and the high-temperature air will have low density, which will reduce the fuel injection pulse width and cause the mixed steam to be too thin. The higher the temperature of the intake air temperature sensor, the more concentrated the mixed steam will be. The open circuit or poor grounding of the sensor will cause the mixed steam to be too lean and cause difficulty in starting.

What are the links to check the resistance of the new energy vehicle temperature sensor and the ECU connection line?

Use a high-impedance multimeter to electrically block, and measure the resistance value of the two connection harnesses between the automobile water temperature sensor and the ECU (the resistance value between the sensor signal terminal and the ground terminal and the two terminals of the corresponding ECU), and the circuit should be connected. If the circuit is non-conducting or the resistance value is greater than the specified value, it means that the sensor harness is open or the connector is in poor contact and should be further checked or replaced.

The advancement of science and technology has spawned a variety of new automotive auxiliary equipment and promoted the transformation of the industry. The innovation of the temperature sensor of new energy vehicles has enhanced the safety of the vehicle a lot, ensured the safety of the personnel in the vehicle, and alleviated people's worries about the safety of the vehicle.
