We can learn these advanced technology , the structure , working principle and maintenance of knowledge to lay a good foundation for our future. Based on corolla 1ZR electronic-controlled engine, design and research , for the auto repair industry or automotive related majors from personnel of course of study can be applied to automobile disassembling operation training teaching of engine on this subject . First of all, we should know some knowledge such as the basic structure, principle of engine. And then on the basis of the design, the experimental platform by the panel circuit, control circuit, fault points and bench and other parts will have the function of the dismantling and inspection. Next has carried on the experiment table and control part of the design and draw the circuit diagram of electric control system for teaching and using CATIA software entity design for test bench. In view of the teaching, related to the fault diagnosis system is developed. The system panel terminals equipped with detection can direct detection sens
