0173-00 High Exhaust Gas Temperature Derate
产生此代码的情况:
该代码说明发动机额定功率已下降，以防排气温度过高。
发动机控制模块 (ECM) 将根据下述传感器送来的输入计算排气温度：
- 大气压力传感器
- 进气温度传感器
- 发动机转速/正时传感器
系统响应:
发动机额定功率下降超过 4% 后即记录该代码。 发动机只能降低额定功率到允许排气温度降至容许范围内的程度。 如果存在该事件代码的话，检查发动机指示灯不亮。
ECM 会使发动机额定功率下降。
测试步骤 1. 与驾驶员交流
注: 不需要进行发动机修理。
- 确定导致该故障诊断代码的状况。
预期结果:
发动机在重载和/或爬陡坡情况下运转。
结果:
- 正常 - 停止
