Throttle opening degree is used to convert a voltage signal , controlling the fuel injection quantity by the ECU . Commonly used switching linear throttle position sensor and Car Temperature Sensor two of them switching the throttle position sensor although the structure is relatively simple, but its output is discontinuous . In addition to the three , for automotive engine electronic control sensor is also an oxygen sensor , temperature sensor, knock sensor , Crankshaft Positioning Sensor, speed sensor . Any use of modern automotive electronic control systems or devices , are inseparable from sensors, such as automatic transmission, anti-lock brake systems, drive-slip system. Especially in recent years , more and more car electronic devices , such as security alarm devices, communication devices , entertainment devices and to improve comfort and reduce fatigue using auxiliary driving device and so on. Of course, the domestic automobile electronic control technology has just started , mainly in the engine electronic control , and as such , automotive sensors in our country will have a broader space for development.
