1.发动机传感器的使用要点氧传感器有多种形式,接线有1根、2根或者3根、4根。后两种是装有加热元件的加热式氧传感器。使用时需要按照规定里程或时间间隔定期检测或更换。新型的能保证行驶8-11万km。检测时有的要求用扫描仪器来测量氧传感器的输出,有的可用数字电压表检测输出电压信号随混合气浓度变化的情况,以及ECU对电
1, the use of the engine sensor oxygen sensor has many forms, the wiring has 1, 2 or 3, 4. The last two are heated oxygen sensors equipped with heating elements. Need to use regular intervals or in accordance with the provisions of regular testing or replacement. The new type can guarantee 8-11 million km. Some of the requirements of the test using a scanning instrument to measure the oxygen sensor output, and some digital voltmeter can be used to detect the output voltage signal with the mixed gas concentration changes, and ECU on electricity
