Engine sensors are an essential part of modern cars. There are nine main sensors on cars, and they have different functions.

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

2. The intake air pressure sensor is installed on the intake manifold to detect the change of negative pressure in the intake manifold to sense the intake air volume of the engine.

3. The engine speed and camshaft position sensor is the most important sensor in the engine centralized control system. It is a signal used to measure the engine speed and confirm the crankshaft position.

4. The throttle position sensor is installed on the throttle body. It includes a linear throttle potentiometer and an idle switch. The former supplies the ECU to control the fuel injection amount and ignition advance, and supplies the latter to the ECU to sense the throttle position. idling state.

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

6. Intake air temperature sensor, its function is that when the engine is working, the air mass entering the engine is related to the intake air temperature and atmospheric pressure. When the intake air temperature is low, the air density is high and the mass of the same gas is On the contrary, when the inlet air temperature is high, the mass of the same gas is smaller.
