Small body plays a big role, and the basic knowledge of automobile oxygen sensor is stored

There are many kinds of sensors in cars. If each sensor fails, cars will have problems of one kind or another. What is a vehicle sensor? The vehicle sensor is the input device of the automobile computer system. It converts various working condition information during the automobile operation, such as vehicle speed, temperature of various media, engine operating condition, etc., into electrical signals and sends them to the computer so that the engine is in the best working condition. Once a sensor fails, the corresponding device will not work normally or even not work. The role of the sensor in the car is extremely important. Today, let's talk about oxygen sensors.

Can I save fuel by changing the oxygen sensor?

The fuel can be saved by replacing the oxygen sensor, but the specific amount is affected by the vehicle condition and driving habits. For the oxygen sensor, it mainly detects the oxygen content in the exhaust, and ecu corrects the fuel injection quantity according to the data it sends out. The following information is about the failure of the oxygen sensor:

10 kinds of oxygen sensor fault manifestations, causes and troubleshooting

The oxygen sensor transmits the measured value of air fuel ratio in the automobile engine to its PCM/ECU automobile computer for corresponding adjustment. It also takes into account atmospheric pressure, altitude and ambient/engine temperature (among other things) to determine whether the engine is burning a lean mixture or a rich mixture.

Can the automobile oxygen sensor be replaced? Can you change it yourself? Read it and understand it directly!

It requires certain professional knowledge and tools to judge the failure and replace the oxygen sensor. The installation position of the oxygen sensor varies according to the model, and the difficulty of replacing the oxygen sensor varies. It is generally recommended that old drivers do it, or have a certain theoretical basis.

What is the function of automobile oxygen sensor

The function of the automobile oxygen sensor is to detect whether there is excessive oxygen in the exhaust gas of the engine after combustion, that is, the oxygen content, and convert the oxygen content into a voltage signal to the engine computer, so that the engine can complete the closed-loop control of the excess air coefficient. The three-way catalytic converter has the highest conversion efficiency for hydrocarbon, carbon monoxide and nitrogen oxides in the tail gas, and can best transform and purify the discharged pollutants.

The fuel consumption of the car increases sharply, which is related to the oxygen sensor? After reading, I understand!

Many drivers will have such questions. It is clear that after only a few years of buying the car, why is the fuel consumption increasing, or even abnormal? What does this have to do with it? In fact, a damaged oxygen sensor will indeed lead to an increase in fuel consumption. The oxygen sensor is divided into front oxygen and rear oxygen. The front oxygen monitors combustion and the rear oxygen monitors whether the three-way catalytic converter works normally.
