What are the types of automotive sensors

Automobile sensors are the input devices of automobile computer systems. Their function is to convert various working condition information during automobile operation, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmit them to the computer so that the automobile is in the optimal state. Best working condition.

The types of sensors on cars include: throttle position sensor, intake air pressure sensor, crankshaft position sensor, air flow sensor, knock sensor, fontanelle sensor, engine speed sensor, vehicle speed sensor SPD, etc. These sensor types play a vital role in cars, helping them drive smarter and run more efficiently.

The throttle position sensor is a sensor used to detect the throttle opening. Its output signal can reflect changes in engine load and is very important for engine control. The intake pressure sensor is used to detect the intake pressure and help the engine control unit adjust the fuel injection amount to ensure normal engine operation. The crankshaft position sensor can detect the position and speed of the crankshaft and plays an important role in the engine ignition and fuel supply system. The air flow sensor detects air flow and helps the engine control unit calculate the required amount of fuel injection. The knock sensor can detect engine knock and help the engine control unit adjust the fuel injection amount to ensure normal engine operation. The fontanelle sensor can detect the engine coolant temperature and help the engine control unit adjust the water temperature of the cooling system to ensure normal engine operation. The engine speed sensor can detect the engine speed and help the engine control unit adjust the fuel injection amount and ignition timing. The vehicle speed sensor SPD is used to detect vehicle speed and help the vehicle control system adjust the vehicle's acceleration and braking.

In general, there are many types of automotive sensors. When determining sensor failure, you should not only consider the sensor itself, but the entire circuit with the problem. Failure of car sensors may cause the car to fail to work properly. Therefore, during car repair and maintenance, regular inspection and maintenance of sensors are required. At the same time, with the continuous development of automobile technology, more and more new sensors are being applied to automobiles, making automobiles increasingly intelligent.
