E1044 High Intake Manifold Pressure
产生此代码的情况:
电子控制模块 (ECM)检测到进气歧管空气压力较高。
系统响应:
控制面板显示屏会出现一条警告。
记录该代码。
E1044-1
控制面板显示屏会出现一条警告。
E1044-2
发动机功率减额 20%。
此事件代码将检测高于触发点的进气歧管压力,该触发点由 ECM 软件定义。
测试步骤 1.
- 检查电子维修工具上是否存在激活的诊断代码或记录的诊断代码。 在继续进行本程序之前,诊断并排除所有代码。
- 检查空气滤清器有无损坏。 如有必要,更换损坏的空气滤清器。 请参考操作和保养手册。
- 检查进排气系统有无阻塞和/或漏气。 请参阅系统操作,测试和调整。
- 检查废气旁通阀是否正常工作。 请参阅系统操作,测试和调整。 如果 C6.6 发动机上的废气旁通阀执行器有故障,则更换废气旁通阀执行器。 请参阅拆解和组装。 如果 C4.4 发动机上的废气旁通阀执行器有故障,则更换涡轮增压器。 请参阅拆解和组装。
- 确认 FLS 正确。
结果:
- 正常 - 停止
