With the in-depth development of modern electronic technology and the continuous breakthrough of artificial intelligence,the degree of automotive electronics is constantly improving,and the electronic control system used in the engine as the core of the automobile has become increasingly complex.The many sensors,actuators and highly complex electronic control units(ECUs)involved in electronically controlled engines are used to improve the overall performance of the vehicle and inject new impetus into the development of automobiles,but the deepening of the degree of electronization of automobile engines also brings new challenges to maintenance personnel.This paper will explore the technical level of electronically controlled engine fault diagnosis and maintenance,use electronically controlled engine fault diagnosis and maintenance technology to solve common engine fault maintenance examples,summarize fault diagnosis methods,and provide some valuable experience for automotive electronically controlled engine maintenance personnel.
