0108-04 Barometric Pressure voltage low (26)
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况：
- 大气压力传感器送来的信号电压低于 0.2 VDC 超过 30 秒。
- ECM 至少已通电两秒钟。
- 发动机不运转或已运转超过十秒钟。
系统响应:
ECM 将恢复大气压力到 100 kPa (15 psi) 的缺省值。 卡特彼勒电子技师 (ET) 上"大气压力"状态的旁边会显示"诊断"。
该代码为激活状态的同时，发动机功率可能偏低。
测试步骤 1. 进行以下的诊断步骤: 发动机压力传感器断路或短路 - 测试
结果:
- 正常 - 停止
