MID 018 - CID 0555 - FMI 02 Noisy Oxygen signal
产生此代码的情况:
氧气标定正在进行中或发动机正在运转。 发生下列任一状况：
- 氧气继电器断断续续地通电和断电。
- 自氧气缓冲器至电子控制模块之间的接线存在间歇性故障。
- 自氧气传感器至氧气缓冲器之间的接线存在间歇性故障。
- 氧气缓冲器出故障。
- 氧气传感器出故障。
- ECM出故障。
系统响应:
如果氧气标定正在进行中，氧气标定将会终止。 现有的标定数值将保持不变。
如果发动机正在运转，排放可能会受到不良影响。
该诊断代码可以在数字诊断工具(DDT)、发动机控制模块(ECM)或卡特彼勒电子技师(Cat ET)上查看到。
如果需要进行的氧气标定没有完成，发动机性能和排放将会受到影响。
测试步骤 1. 进行以下的诊断步骤: 氧气传感器信号
结果:
- OK - 停止
