| Abstract: | Automobile electronic control technology makes fault-diagnosing increasingly rely on fault codes,data flow,waveform analysis and some other means.Luckily,the waveform analysis of electronic signals can greatly make up for the lack of fault codes and data flow,so it has been given much attention nowadays.The paper analyzes how to apply the waveform analysis of oxygen sensor to the engine fault diagnosing. |
