事件代码    
代码和描述     产生此代码的状况     系统响应    
174-0 燃油温度传感器:高     燃油温度高于触发点规定的延迟时间。     记录该代码。    

可能原因

  • 燃油压力调节阀

  • 燃油油位

  • 燃油管

  • 发动机过热

  • 燃油温度传感器

建议的措施

燃油压力调节阀

燃油压力调节阀工作不正常可能会导致高燃油温度。 如果怀疑有故障,检查回油压力调节阀。 清除所有可能影响调节阀正常工作的污染物或碎屑。 如果存在碎屑,找出污染物的来源。 如果回油压力调节阀磨损或损坏,更换该阀。

燃油油位

确保燃油箱含有足够的燃油。 燃油箱油位下降时,燃油温度以便会升高。

燃油管

回油管受阻可能会导致燃油温度非常高。 确保流到燃油箱的回油没有受阻。

发动机过热

燃油通过缸盖中的油道供应至喷油器。 环境空气温度异常高可能会导致燃油温度达到触发水平。 发动机过热可能会导致燃油温度达到触发水平。

燃油温度传感器

确认燃油温度传感器安装正确。 如果怀疑传感器存在电气故障,请参阅故障诊断与排除, "传感器信号(模拟、有源)- 测试"。
