It is manufactured to exacting specifications and is a good alternative to the old version. 【Practical Accessories】 The pressure sensor measures the absolute pressure change in the intake manifold according to the state of of the engine and converts it into a voltage to determine the amount of fuel injection of the injector. In case of pressure sensor failure, it will be difficult to start the car, stop engine, slow down idle etc. The pressure sensor is therefore an important and practical accessory. Stable performance: the pressure sensor is designed according to the principle of piezo technology. Its interior is mainly composed of a well-sealed elastic diaphragm and an iron It is equipped with an integrated circuit amplifier, which has a high output and good anti-interference performance. The pressure sensor optimizes the design of the magnetic circuit and replaces it with a high magnetic magnet for more stable performance. 【Excellent and Durable】The automotive pressure sensor is made of high quality ABS material. ABS has good wear resistance, high temperature resistance, corrosion resistance and aging resistance, ensuring maximum strength and durability, so that the pressure sensor has a long service life.
