CID 0042 FMI 11 Inject Actuation Control Valve open/short
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:
- 开路
- 接地短路
- 蓄电池正极短路
- 发动机运转时电磁阀两端之间短路。
系统响应:
ECM 将会循环接通和断开喷油作动系统的控制阀。 发动机运转时,ECM 将会每秒钟数次循环接通和断开控制阀。
如果喷油作动系统控制阀的信号线对地短路的话,发动机将会停止运转。
如果控制阀的回路线对地短路的话,可能会存在以下情况:
- 发动机可能会继续运转。
- 怠速可能会不稳。
测试步骤 1. 进行以下的诊断步骤: 喷油作动压力控制阀电路 - 测试
结果:
- 正常 - 停止
