What sensors are there in the engine?

Sensors in the engine include: air flow sensor, throttle position sensor, accelerator pedal position sensor, air temperature sensor, coolant temperature sensor, etc. Among them, the air flow sensor is used to measure the air flow entering the engine, which is generally installed on the air bypass channel, and the throttle position sensor is installed on the throttle body, including a linear throttle potentiometer and an idle switch. Engine sensor is an indispensable part of automobile, which is mainly divided into crankshaft position sensor and camshaft position sensor according to position, electromagnetic induction sensor, Hall effect sensor and photoelectric effect sensor according to application technology.
