CID 0172 FMI 03
产生此代码的情况:
电子控制模块（ECM）可检测以下状况：
- 来自进气歧管空气温度传感器的电压高于 4.95 DC 超过 8 秒钟。
- 发动机冷却液温度高于 −10 °C (15.0 °F)。
- ECM 至少已通电两秒钟。
- 诊断代码0168-01 未激活.
系统响应:
ECM 使用的进气歧管空气温度默认值是 70 °C (158 °F)。 电子维修工具在"进气歧管空气温度"状态旁显示"电压较高"。
控制面板显示屏会出现一条警告。 ECM 将会记录此诊断代码。
- 稳定性差
- 冷却不佳运行
- 冒白烟
- 黑烟
- 负载工况下加速性能不佳
断路或是与另一个电源短路可能导致该诊断代码。
测试步骤 1. 进行以下的诊断步骤: 发动机温度传感器开路或短路 - 测试
结果:
- 正常 - 停止
