Engine sensor is an indispensable part of modern automobile. There are nine sensors in the car, and their functions are different.

1. The air flow sensor is used to measure the air flow entering the engine and is installed on the air bypass channel.

Secondly, the intake pressure sensor is installed on the intake manifold, and the intake air volume of the engine is sensed by detecting the negative pressure change of the intake manifold.

3. The engine speed and camshaft position sensors are the most important sensors in the engine centralized control system, which are used to measure the engine speed and confirm the crankshaft position.

4. The throttle position sensor is installed on the throttle body, including a linear throttle potentiometer and an idle switch. The former is used by ECU to control the fuel injection quantity and supply the latter before ignition. The ECU detects that the throttle is idling.

5. The coolant temperature sensor is installed on the water jacket of the engine cylinder head. Used to measure the temperature of engine coolant.

Six, the air temperature sensor, the role is that when the engine is working, the air quality entering the engine is related to the intake temperature and atmospheric pressure. When the inlet temperature is low, the air density is high and the mass of the same gas is large. On the contrary, when the inlet temperature is high, the mass of the same gas is small.
