P0562 OBD-II: 系统电压低 OBD-II故障代码P0562是什么意思?

OBD-II代码P0562定义为系统电压低。

充电系统的目的是保持理想的车辆电压水平,当车辆在怠速状态且车灯关闭时,该电压水平通常为直流14.1 - 14.4伏。 当动力总成计算机中设置代码P0562时,意味着动力总成计算机或PCM看到的车辆电压低于要求。 当电压水平低于10.0伏超过60秒时,该代码将被设置。当发动机运转时,请保持数秒。

有此故障代码的车辆应送至修理厂进行诊断。 查找修理厂

P0562 症状

  • 发动机检查指示灯点亮
  • 电池指示灯可能点亮
  • 车辆可能无法正常换档
  • 燃油经济性降低
  • 在特殊情况下,驾驶员未发现任何不利条件
  • 在某些情况下,可能会出现性能问题,如停车时熄火和/或类似失火的症状。

触发P052代码的常见问题

  • 交流发电机故障
  • 报警器接线或连接器故障
  • 从交流发电机到蓄电池的B+蓄电池电缆故障
  • 充电系统接地不良
  • PCM接线/与交流发电机的连接有缺陷
  • PCM故障
  • 稳压器故障
  • 寄生电池耗电量大
  • 蓄电池和/或电缆故障

常见误诊

  • 电池
  • 启动器

排放的污染气体

  • HCs(碳氢化合物):未燃烧的原燃料液滴,有异味,影响呼吸,导致烟雾。
  • CO(一氧化碳):部分燃烧的燃料,是一种无味的致命有毒气体。
  • NOX(氮氧化物):在阳光照射下导致烟雾的两种成分之一。

P0562 车间和技术人员诊断理论

当诊断P0562代码时,重要的是记录任何其他代码和P0562冻结帧数据。 然后,应该通过试车重复代码设置条件。 一定要检查交流发电机B+端子的电压输出,并检查充电系统的蓄电池电源和接地端子的电压降。 我还喜欢密切关注扫描工具的数据、我在改变发动机负荷、节气门位置、转速和路速时观察,因为有时P0562很难检测到。
