0100-04 Oil Pressure voltage low (24)
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况：
- 来自发动机机油压力传感器的信号电压低于 0.2 VDC 超过 8 秒。
- ECM 至少已通电两秒钟。
- 168-01 ECM 蓄电池电量不足没有激活。
- 232-03 5 伏电源电压过高没有激活。
- 232-04 5 伏电源电压过低没有激活。
- 发动机运行或大气压力高于 80 kPa (12 psi)。
注: 只有在发动机运行时，大气压力低于 79 kPa (12 psi) 才会造成此代码变为激活状态。 在正常电路中，大气压力低会导致信号电压降至 0.2 VDC 的切断点以下。
注: 海拔高于 1900 m (6300 ft) 时，大气压力就会低于 79 kPa (12 psi)。
系统响应:
ECM 将记录诊断代码并触发快照。 当该诊断代码变为激活状态 10 小时后，检查发动机指示灯点亮。 ECM 将 600 kPa (88 psi) 默认为发动机机油压力。
注: 在卡特彼勒电子技师 (ET) 上所显示的发动机机油压力等于发动机机油压力默认值减去大气压力。
无
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
