0164-04 Injection Actuation Pressure voltage low (15)
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况：
- 喷油驱动压力电路电压低于 0.2 VDC 超过 0.6 秒。
- ECM 已通电超过八秒钟。
- 没有启动冷起动模式。
系统响应:
ECM 将指示并记录一个激活的代码。 检查发动机指示灯点亮。
ECM 将恢复到 10 MPa (1450.4 psi) 的缺省值。 卡特彼勒电子技师 (ET) 状态屏上"理想喷油驱动压力"和"实际喷油驱动压力"的旁边会显示 10 MPa (1450.4 psi)。
喷油驱动压力控制阀设定在 0.275 安培上。 喷油驱动压力控制阀的电流设定在固定位置上。 燃油输送受限。
注: 如果喷油驱动压力高于或低于额定充油压力的话，喷油驱动压力传感器就不会低于参考电压的 10% 或高于 90%。
发动机怠速时粗暴运转。
ECM 会限定功率输出在89.5 kW (120.0 hp) 上，同时车速限定在 73 km/h (45 mph) 上。
测试步骤 1. 进行以下的诊断步骤: 发动机压力传感器开路或短路 - 测试
结果:
- 正常 - 停止
