3126B Engines for 322C, 325C, and M325C Excavators and for the 325C Mobile Hydraulic Power Unit Caterpillar


E005 Fuel Filter Restriction Derate

Usage:

3126B 5GG
产生此代码的情况:

当燃油压力持续 10 秒低于 425 kPa62 (psi) 时,激活警告。 当燃油压力持续 10 秒低于 400 kPa (58 psi) 时,发动机开始减额模式。 当燃油压力超过 350 kPa (51 psi) 时,发生最大减额。

系统响应:

Caterpillar 电子技师(Cat ET)将在任何 Cat ET 状态屏幕上的第一个发动机状态箱中显示"发动机减额"。 ECM 可降低发动机功率 35%。 当燃油压力升高,持续 4 秒高于 470 kPa68 (psi) 时,ECM 将恢复全功率。

ECM将会在 Cat 数据链路上产生 EID 005 事件代码。 此诊断代码将会在 Cat ET的诊断屏幕上显示。

此事件代码指示燃油滤清器存在阻塞情况。 这并不表示 CEM 有问题。

测试步骤 1.

更换堵塞的燃油滤清器。

结果:

  • 正常 - 停止
