Abstract
This paper discusses the application of oxygen sensor in electronic control vehicle fault repair and the challenges it faces. Firstly, the basic concept of oxygen sensor is summarized, including its definition, function, structure and type. Then, the application of oxygen sensor in monitoring and controlling engine combustion, optimizing fuel injection, reducing exhaust emission, fault diagnosis and prevention in automobile electronic control system is analyzed in detail. However, oxygen sensors also face challenges in the troubleshooting process, such as the complexity of signal interpretation, the diversity of fault types, the technical requirements of maintenance detection, and the correlation between faults and other systems. In order to cope with these challenges, this paper puts forward the corresponding optimization countermeasures. Firstly, the intelligent level of fault diagnosis is improved by developing adaptive fault identification algorithm, using the Internet of Things technology to realize remote monitoring, and constructing fault prediction and health management model. Secondly, strengthen professional training of maintenance personnel, including technical update training, simulated fault practice training and the establishment of professional certification system. In addition, advanced detection equipment and tools, such as high-precision sensor detection technology, intelligent diagnostic scanning tools and real-time data flow analysis equipment, are introduced to improve the efficiency and accuracy of troubleshooting. Finally, the troubleshooting and diagnosis process of the system is established, including the formulation of standardized operating procedures, the setting of fault code classification and processing guidelines, and the implementation of multi-stage diagnosis process. Through this research, the purpose is to provide valuable reference and guidance for the application of oxygen sensor in electronic control vehicle troubleshooting.
