There are many kinds of sensors in the car, each one has a fault, and the car will have such a problem. What is the vehicle sensor? Automotive sensors are the input device of the car computer system, which put a variety of operating conditions in the car information, such as speed, medium temperature, engine operating conditions, etc., into an electrical signal to the computer , So that the engine is in the best working condition. Once a sensor fails, the corresponding device will work abnormal or not work, the role of the sensor in the car is extremely important. What are the commonly used sensors? A sensor failure will make the car what performance?

Sensor technology restricts the development of China's Internet of things the biggest bottleneck

1, oxygen sensor

The position of the exhaust pipe, the oxygen sensor failure, so that ECU can not be informed of the amount of fuel injected is correct, resulting in the mixer is not too thick or too thin concentration, inadequate combustion, reduce engine power and increase emissions pollution. The longer the car the more problems? We ignore the details: the car sensor

2, wheel speed sensor, usually installed in each wheel hub. Once the fault, ABS will fail. The longer the car the more problems? We ignore the details: the car sensor

3, air flow meter, generally installed in the air filter and throttle body, but the failure of the engine speed can not rise. The longer the car the more problems? We ignore the details: the car sensor

4, the water temperature sensor, generally located next to the thermostat, but the fault, the engine will be difficult to start the cold start, idle unstable operation, and lack of motivation to accelerate. The longer the car the more problems? We ignore the details: the car sensor

5, the crankshaft position sensor and the camshaft position sensor are generally installed in the rear of the crankshaft pulley or large flywheel and camshaft in the vicinity of the front or rear, the two complement each other, while working for the engine to provide a good guarantee of normal operation. One of the faults, the engine will not start.

6, accelerator pedal position sensor

General and accelerator pedal one, but the fault, the engine can only be in idle state operation. The longer the car the more problems? We ignore the details: the car sensor

7, odometer sensor

Generally installed on the gearbox, but the fault, the odometer does not take the word. The longer the car the more problems? We ignore the details: the car sensor

8, oil pressure sensor

Generally installed in the engine side of the cylinder, but the fault, the oil pressure is not enough time on the dashboard light will not light. No oil alarm, if the real lack of vehicle oil, we are also hard to know without going to add oil, it is likely to cause damage to the engine The longer the problem the more? We ignore the details: the car sensor

10, ABS sensor

Generally installed in the wheel bearing above each one, but the fault, the emergency ABS does not work, the emergency brake will lock the wheels, if the encounter slippery road surface, prone to drift tail, affect driving safety age The longer the problem the more we ignore the details: the car sensor

11, airbag sensor

Generally installed in the front of the car (front and rear driver's seat), the side (the car front and rear) and roof three directions, but damaged, needless to say, in case of emergency the airbag will not pop up. General sensor failure, the relevant fault lights will light up, find the cause, the sensor failure, we must pay attention to, which is closely linked to traffic safety, after all, safety first.

12, intake pressure sensor, usually installed next to the throttle, but the fault will cause ignition difficulties, idle speed instability, acceleration and other problems longer car longer The more the problem we ignore the details: Automotive sensors

13, Throttle position sensor, installed in the throttle body, but the failure will cause the engine idle speed is not normal, the engine jitter and acceleration response lag. The longer the car the more problems? We ignore the details: the car sensor

14, the intake air temperature sensor, usually installed in the throttle behind, but the fault engine mixture is too thick or too dilute, a direct result of cold start difficult, and instable idle longer age more problems? We ignore the details : Car sensor

15, knock sensor, usually installed in the engine cylinder wall, but the fault, the engine fault light will be on, the engine will appear "self-protection phenomenon", affecting the normal driving.

The car is a "complex" with tens of thousands of components, a variety of sensors to make people look dizzy, each sensor failure, the car will be greatly reduced the normal operation!
