3054E 发动机的机油压力图




图 2g01376445

3056E 发动机的机油压力图

电子控制模块(ECM)可检测以下状况:

  • 发动机至少已经运转了 5 秒钟。

  • 发动机转速至少为 350 RPM。

  • 发动机机油压力低于低机油压力阈值超过 2 秒。

  • 100-03 "机油压力与蓄电池正极间开路/短路"处于非激活状态。

  • 100-04 "机油压力与接地间短路"处于非激活状态。

  • 100-10 发动机机油压力传感器变化率异常未激活。

系统响应:

ECM 将会记录该事件。 当机油压力升至阈值以上 21 kPa (3 psi) 持续至少 4 秒时,ECM 将复位警告。

  • 发动机润滑系统可能有问题。

  • 发动机机油压力传感器可能故障。

测试步骤 1. 检查有无现行诊断代码

  1. 启动电子维修工具。

  1. 把钥匙开关转到接通位置。

  1. 检查有无任何活动或记录诊断编码。

预期结果:

应没有任何诊断代码出现。

结果:

  • 确定 - 没有任何诊断代码出现。 转至测试步骤 2。

  • 异常 - 有诊断代码出现。

    修复: 修理产生诊断代码的故障。 请参阅故障诊断与排除, "诊断代码的故障诊断与排除"中的相应主题。 确认修理消除了故障。

    停止

测试步骤 2. 检查发动机润滑系统

  1. 对发动机润滑系统进行检查。 请参阅故障排除, "发动机机油压力低"。

预期结果:

发动机润滑系统中没有故障。

结果:

  • 确定 - 发动机润滑系统中没有故障。 可能存在间歇性故障。

    修复: 监测发动机的运行。 如果确定了间歇性故障,修理故障。 确认修理消除了故障。

    停止

  • 异常 - 发动机润滑系统中有故障。

    修复: 排除故障。 确认修理消除了故障。

    停止
