0042-11 Injection Actuation Pressure output fault
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况：
- 蓄电池电压高于 9 DCV。
- 驾驶员处于接通位置时，ECM 检测到喷油驱动压力控制阀的电流偏高超过 120 毫秒。
系统响应:
发动机运转，并且故障代码为激活状态时，ECM 将循环工作喷油驱动压力控制阀接通和断开。 喷油驱动压力控制阀将恢复到 7.5 MPa (1087.80 psi) 的缺省值。
卡特彼勒电子技师 (ET) 上"喷油驱动电流"状态的旁边会显示 31%。
检查发动机指示灯点亮。
发动机可能运转不平稳。 发动机功率可能偏低。 该故障诊断代码可能会导致发动机停机。
测试步骤 1. 进行以下的诊断步骤: 喷油驱动压力控制阀电路 - 测试
结果:
- 正常 - 停止
