| 摘要： | The "Catalytic Converter Efficiency" Diagnostic Trouble Codes (DTCs) P0420 and P0430, are among the top 10 DTCs technicians face. And while the description might imply a failed converter, odds are the ultimate fault lies somewhere else. The catalytic converter is the last stop for the exhaust gasses generated by the engine during operation. It is here that the last remaining pollutants are cleaned up before finally exiting the tailpipe. There are three ways a converter can fail: Overheated, melted, or a broken substrate in the converter. This is usually caused by any factor that affects the engine's air/fuel mixture and the resulting feed gasses being sent to the converter. Even slight variations will cause the converter temperature to rise significantly. |
