Is the front oxygen sensor common to all models?

As long as the model is the same, the oxygen sensor with the same plug can be universalBecause the function of the oxygen sensor is the same, no matter the model.

The oxygen sensor is mounted behind the exhaust manifold, one in the front and one in the front and one in the front. Automotive oxygen sensor is a key sensing component in the EFI engine control system, which is a key component to control automobile exhaust emissions, reduce environmental pollution of automobiles, and improve the fuel combustion quality of automobile engines.

The oxygen sensor is a measuring element that uses ceramic sensing elements to measure the oxygen potential in various heating furnaces or exhaust pipes, calculates the corresponding oxygen concentration by the principle of chemical equilibrium, monitors and controls the combustion air-fuel ratio in the furnace, and ensures that the product quality and exhaust emissions meet the standards.

Is it necessary to change the rear oxygen sensor

The rear oxygen sensor will not have much impact if it is not replaced, and the general rear oxygen sensor is mainly to feedback the data after combustion to form a computer to adjust the concentration of the mixture, improve the emission because there is a heating resistance wire, so it is easier to break, generally with a rear oxygen sensor in about 200. It is generally recommended to replace it.

The role of the rear oxygen sensor is to improve fuel economy and reduce exhaust emissions (in terms of fuel consumption and environmental protection, it does not affect driving safety). The accessories of the 4S store ** is 1061 yuan (the accessories of the 4S store ** are unified nationwide) If you go to the accessories store outside, it is difficult to buy the genuine product, and the quality cannot be guaranteed.

As long as the appearance is almost the same, the screw mouth is the same, the plug is not right, the wire is cut and connected correctly, and the data can be read out by computer measurement after changing the car, and there is no fault code can be universal, although the oxygen sensor is said to be a precision part of the car, but it is not as mysterious as everyone imagined.

Not universal, each model is different.

Summary. Hello, I'm glad to answer for you I'm your car master exclusive technician Concentrate on your intentions and sincerely answer your car questions, and find solutions and methods for you to ask as follows: some of the front oxygen sensor and rear oxygen sensor accessories are the same, some are different, it is divided into three lines, and four lines, you need to take a look at your oxygen sensor, is the front and rear two wiring harnesses the same?

If it's the same, it's normal, but the length of their wiring harness is different. In the case of the oxygen sensor, it is mainly used to detect the concentration of the mixture to control the fuel injection, and in the case of the oxygen sensor, it is mainly to detect the conversion efficiency of the three-way catalysis.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

If it's the same, it's OK to use it normally, but the length of their wiring harness is different.

In the case of the Donggao oxygen sensor, it is mainly used to detect the concentration of the mixture to control the fuel injection, and in the case of the oxygen sensor, it is mainly to detect the conversion efficiency of the three-way catalysis.

Because the front oxygen sensors are all **.

The oxygen sensor can be bought from the original factory, but it must be cheaper. The engine burns oil, the air-fuel ratio is too thick and too thin, and carbon is deposited.

Serious will cause the oxygen sensor to be poisoned and fail, resulting in fuel consumption, exhaust gas and odor.

Brief introduction. Pacific Automotive Network.

The automotive oxygen sensor is the key feedback sensor in the EFI engine control system, which is used to control the exhaust gas of the car.

Emissions reduce the environmental pollution of automobiles and improve automobile engines.

The oxygen sensor, a key component of fuel combustion quality, is installed on the engine exhaust pipe. Located in the three-way catalytic converter.

The front one is called the pre-oxygen, and the posterior oxygen is located behind the catalytic converter, but the front and rear oxygen sensors have different functions.

The function of the front oxygen sensor is to feedback the oxygen content in the exhaust gas to the engine computer during the "closed-loop control", and the engine computer corrects the amount of fuel injection according to this signal.

The rear oxygen sensor is installed in a three-way catalytic converter.

After the rear, the oxygen content of the rear of the three-way catalytic converter is fed back to the engine computer, and the engine computer compares the signals of the two oxygen sensors, and the signal of the front oxygen sensor is higher than that of the rear oxygen sensor under normal circumstances, and if the signal of the two oxygen sensors is the same, it proves that the three-way catalytic converter fails.
