| J1939 代码和说明 | 产生此代码的状况 | 系统响应 |
| 95-15 发动机燃油滤清器压差：高 - 最低严重程度 (1) | 过滤后的燃油的压力与未经过滤的燃油的压力之差大于触发点压力。 | 记录该代码。 ECM 可能会使发动机减额或停机。 |
| 95-16 发动机燃油滤清器压差：高 - 中等严重程度 (2) | ||
| 95-0 发动机燃油滤清器压差：高 - 最高严重程度（3） | ||
可能原因
- 燃油滤清器滤芯
建议的措施
燃油滤清器滤芯
- 更换燃油滤清器滤芯。
- 充注燃油系统。 参考操作和保养手册以了解该信息。
- 重新起动发动机，检查有无现行事件代码。
- 如果上述事件代码保持现行状态，则应该检查有无与燃油压力传感器有关的记录的诊断代码。 如果存在记录的代码，则检查连接至燃油压力传感器的线束或配线中有无间歇性故障。 参考故障排除, "电气接头 - 检查"以了解与间歇性电气故障相关的信息。
