Based on the research and comparison of the main contents and measurement methods for the inspection and Maintenance Program in the United States, the European Union, and China, and the analysis of the OBD inspection in China, it is found that the in-use vehicle measurement method in our country has covered the mainstream measurement methods, however, the overall system design still lacks corresponding standards and technical support for maintenance and closed-loop supervision, the cause of the OBD inspection failure is concentrated the malfunction of the oxygen sensor and three-way catalytic converter.
Key words: In-use vehicle / Inspection and maintenance program / OBD system inspection
