Is it serious that the car sensor is broken? What will happen if the car sensor is broken?

Automotive sensors can be divided into two categories: environmental monitoring and body perception: environmental monitoring sensors are used to detect and perceive the surrounding environment, and are necessary for automatic driving; body perception sensors are used to obtain body information, such as tire pressure, oil pressure, Vehicle speed, etc., are the basic sensors necessary to maintain the normal, stable and safe driving of the car. The main sensors are:

Air flow sensor

The air flow sensor is generally installed on the air filter and the throttle body to measure the amount of air sucked in by the engine, which is converted into an electrical signal and provided to the ECU as a reference signal for the fuel injection time. If a malfunction occurs, the car will experience idling jitter, weak acceleration, increased fuel consumption, and black smoke from the exhaust pipe, which will affect the performance of the car's engine.

ABSsensor

The ABS sensor sensor is generally located at the position of the tire close to the bearing.Wheel hubThe outside of the bearing and the inner ring of the brake disc are used to monitor the speed of the vehicle. In the case of sudden braking, the wheel speed is fed back to the brake system. The brake system controls the wheel to rotate in a restrained manner to achieve the best braking effect;If a malfunction occurs, the ABS will fail. During emergency braking, the wheels will lock up, causing the wheels to slip out of control.

Throttle position sensor

Throttle position sensor is installed on the throttle to detect the opening of the throttle. Through the linkage with the throttle through the lever mechanism, it measures the voltage signal of the throttle opening angle, and transmits the signal to the ECU as the fuel injection amount and the ignition advance angle. Corrected reference signal. If a malfunction occurs, it will cause abnormal engine idling, engine jitter, and delayed acceleration response.

Crankshaft position sensor and camshaft position sensor

The crankshaft position sensor and the camshaft position sensor are respectively installed behind the crankshaft pulley or near the large flywheel and in front or behind the camshaft. The two complement each other and work to ensure the normal operation of the engine. If a malfunction occurs, the engine will not start.

Oxygen Sensor

Oxygen SensorInstalled on the exhaust pipe, it is used to detect the oxygen content in the engine exhaust, to determine whether the gasoline and air are completely combusted, and to perform closed-loop control of the fuel injection volume. If a malfunction occurs, the ECU cannot know whether the amount of gasoline injected is correct, resulting in inconsistent mixture concentration and insufficient combustion, reducing engine power and increasing emission pollution.
