Why Does the Oxygen Sensor Keep Failing

Reasons for oxygen sensor failure are as follows: 1. Ceramic fracture of the oxygen sensor. The ceramic in oxygen sensors is hard and brittle, and strong impacts or airflow can cause it to crack and fail. Therefore, special care must be taken during handling, and timely replacement is necessary if issues are detected. 2. Burnout of the heater resistance wire. For heated oxygen sensors, if the heater resistance wire burns out, it becomes difficult for the sensor to reach its normal operating temperature, rendering it ineffective. 3. Oxygen sensor poisoning. Oxygen sensor poisoning is a common and hard-to-prevent issue, especially with frequent use of leaded gasoline in vehicles. Even new oxygen sensors may only last a few thousand kilometers. In cases of mild lead poisoning, running a tank of unleaded gasoline can help remove lead deposits from the sensor's surface and restore normal operation. However, often due to excessively high exhaust temperatures, the lead penetrates deeper, hindering oxygen ion diffusion and causing the sensor to fail, necessitating replacement. 4. Carbon buildup. Poor engine combustion can lead to carbon deposits forming on the oxygen sensor's surface, or oil and dust entering the sensor, blocking external air from reaching its interior. This results in incorrect signal output, preventing the ECU from accurately adjusting the air-fuel ratio. Carbon buildup primarily manifests as increased fuel consumption and significantly higher emission levels. If the deposits are cleaned, normal operation can be restored.

Can China 5 Vehicles Still Be Registered After the Implementation of China 6?

When the China 6 emission standard is implemented in a local city, China 5 vehicles can no longer be registered. If you want to purchase a China 5 vehicle, you need to verify with the local vehicle management department before making a decision. However, after the implementation of the China 6 standard, already registered China 5 vehicles can still be driven, and China 5 vehicles can continue to be registered. The China 6 emission standard has been implemented in some major cities since July 1, 2019. After implementation, only vehicles meeting the China 6 emission standard can be registered. All vehicles sold and registered must comply with the China 6 emission standard requirements. Vehicles below the emission standard will be prohibited from being sold, registered, or transferred. China 4 and China 5 emission vehicles can only be scrapped or relocated to regions where the China 6 standard has not yet been implemented. The China 6 emission standard is implemented in two phases: China 6A and China 6B. China 6A requires all vehicles sold and registered to comply with the China 6A standard from July 1, 2020. China 6B requires all vehicles sold and registered to comply with the China 6B standard from July 1, 2023.

Can Blue License Plates Be Switched Back After Changing to Green Ones?

After changing from blue license plates to green ones, it is not possible to switch back to blue plates. The differences between blue and green license plates are as follows: Different Vehicle Types: Blue plates are for conventional fuel-powered vehicles, while green plates are for new energy vehicles. Green plates apply to pure electric vehicles and plug-in hybrid vehicles. There are two types of green plates: one is gradient green, and the other is a yellow-green dual-color combination. Gradient green plates are used for new energy passenger cars, while the yellow-green dual-color plates are used for buses. Green plates indicate new energy vehicles, and the number of digits on green plates has increased from five to six. These plates use only two letters, D and F, where D represents pure electric vehicles and F represents hybrid vehicles. Different Technologies Used: Green plates incorporate anti-counterfeiting technologies such as two-dimensional barcodes and anti-counterfeiting watermark marks, which enhance the plates' anti-counterfeiting performance to some extent. With the continuous development of automotive production technology, new energy vehicles are gradually entering the automotive market, and consumer demand for them is increasing. Green license plates are more common in many large cities with license plate restrictions, reflecting the development trend of new energy vehicles. Additionally, new energy vehicle plates in different regions enjoy various privileges, such as exemption from traffic restrictions based on license plate tail numbers.

What does the odometer reading on the dashboard mean?

The odometer reading on the dashboard refers to two types of mileage: one is the total mileage of the vehicle, which cannot be reset and is displayed prominently on the dashboard. The other is the trip mileage, which can be reset and is displayed smaller, used to record the vehicle's mileage over a certain period. For example, resetting the trip mileage after maintenance can help track when the next maintenance is due. Principle of the vehicle odometer: The vehicle odometer is a digital display dashboard that operates based on the rotation of an electronic counter drum wheel, which meshes with the worm gear on the speedometer's rotating shaft, causing the drum wheel to rotate. Its advantage is that when the upper drum wheel completes a full rotation, the lower drum wheel rotates 1/10 of a turn. Like the speedometer, modern odometers are also electronic, obtaining mileage data signals from the speed sensor. The accumulated mileage data of an electronic odometer is stored in non-volatile memory, allowing the data to be preserved even when the power is off. Odometer overview: The dashboard displays two odometer readings: one long and one short. The long number represents the total kilometers, which cannot be manually altered and only increases as the vehicle is driven. The short number can be manually reset and is used for counting kilometers, such as the distance from one province to another. There is a control button to reset it to zero and start counting again, which explains the presence of two mileage readings—a very user-friendly feature.

How long does it take to clear the violation status after handling it on 12123?

On the official website of 12123, it takes at least three working days to clear the violation status after handling a traffic violation. After paying the fine for the violation on 12123 and seeing that the processing is completed, generally speaking, due to the delay in the traffic management system's violation query, it takes some time for the system to synchronize after handling the violation. Therefore, it takes at least three working days to clear the status. The elimination of violation records is transmitted through the internal network of the traffic police system, and the data transmission is not necessarily real-time. Therefore, it may take three to five working days after payment for the violation record to be cleared on the external network. Just wait patiently. If it is a local violation record, after paying the fine, the status of the driver and the motor vehicle will be restored to normal in the system of the public security traffic police department. The internet query system is generally updated once a week. If it is a violation record from another location, it will take longer to clear the record after paying the fine. Although the 12123 official website is convenient, there are sometimes issues such as duplicate violation records and untimely processing of violation data. It is recommended to go to the vehicle management office or traffic police team for more stable processing.

What is the difference between Castrol Magnetec and Castrol Edge?

Castrol Magnetec is a semi-synthetic oil, while Castrol Edge is a fully synthetic oil. The specific differences between the two are as follows: 1. In terms of base oil, Magnetec's base oil is made from hydrotreated Group III oil, while the 0W series of Castrol Edge has 100% Group IV base oil, and the 5W series uses a blend of Group IV and hydro-cracked Group III base oils. 2. From the engine's perspective, Castrol Edge provides comprehensive engine protection, with API/viscosity grades of SN/0W-40, SN/5W-40, SN/5W-30, and SN/10W-60. Below is additional information: 1. How to choose engine oil. When selecting engine oil, the main consideration should be its viscosity index. Speed, engine load level, and temperature are the three main factors in choosing viscosity. The higher the speed, the lower the viscosity oil you should choose; the higher the load, the higher the viscosity oil you should choose; and the higher the temperature, the higher the viscosity oil you should choose. 2. How to identify engine oil quality. The quality of engine oil depends on: base oil and additives. The quality of the base oil depends on: crude oil source and refining technology, as well as synthetic process technology.
