CID 0164 FMI 11 Injector Actuation Pressure system fault
产生此代码的情况:
电子控制模块(ECM)检测到下述情况之一时：
- 实际喷油作动压力和理想喷油作动压力相差超过3 MPa (435 psi)。
- 通向喷油作动压力控制阀的电流处在最大或最小输出的时间过长。
注: 诊断编码指示出现了机械故障。 ECM和电子控制系统操作正确。
系统响应:
ECM将会记录诊断编码。 诊断编码可在一个显示模块或卡特彼勒电子技师(ET)上观察到。
- 功率低
- 怠速不稳
- 在正常工作温度下难起动
- 在低于正常工作温度下易起动
注: 此故障可能只在工作温度下发生。 如果系统最近被维修过的话，喷油作动系统内可能有困气。 起动发动机，让发动机在1500 rpm下运转几分钟以便清除困气。
测试步骤 1. 进行以下的诊断步骤: 喷油作动压力 - 测试
结果:
- 故障被排除 - 停止
