P0328 OBD-II: 爆震传感器1电路高 OBD-II故障代码P0328是什么意思?

OBD-II 代码 P0328 定义为爆震传感器 #1 - 电路高输入(单传感器或 1 组)

爆震传感器的作用是提醒动力总成控制模块(PCM)发动机出现 "呯呯 "或 "咚咚 "声,这一点非常重要,因为 "呯呯 "或 "咚咚 "声会产生有毒的氮氧化物气体污染空气,导致酸雨和哮喘等呼吸道疾病。

代码P0328表示1号爆震传感器电路的读数过高,超出了其工作窗口,并且出现故障。

P0328 症状

  • 发动机检查指示灯点亮
  • 加速时发动机跳动
  • 发动机运转温度可能高于正常温度
  • 在极少数情况下,发动机可能不会表现出明显的症状

触发P0328代码的常见问题

  • 爆震传感器故障
  • 爆震传感器电路或连接故障
  • EGR系统故障
  • 冷却系统故障
  • 低空气/燃油比

常见误诊

  • 当代码P0328的原因是冷却系统问题时,更换了爆震传感器
  • 当代码P0328的原因是EGR系统故障时,更换了爆震传感器

动力总成控制模块(PCM)控制点火系统火花提前量,以获得最大功率和燃油经济性。 当爆震传感器向动力总成控制模块(PCM)发出发动机 "呯呯 "声或爆震信号时,PCM所做的第一件事就是改变正时提前量,以可控增量延缓正时提前量,直到爆震传感器停止发出信号。PCM 发现发动机 "乓 "响。

当发动机过多地延缓正时,而爆震信号仍显示发动机正在 "呯呯 "作响时,这是一种不合理的情况。 PCM知道,来自1号爆震传感器电路的信号高于其正常工作窗口、出现故障和/或发动机出现异常情况,如过热或发动机内部损坏。 捕获和记录冻结帧数据,以便了解PCM触发P0328代码时的工作条件。 然后对发动机和冷却系统、冷却液液位/状况和机油液位/状况进行目视检查,以验证代码P0328不是由机械系统故障引起的。 然后起动发动机并转几圈,看其工作是否正常、用数据流扫描仪试车,密切注意1号爆震传感器PID和正时提前量PID。 1号爆震传感器电路工作情况如何? 当发动机不爆震时它是否发送信号? 如果是,找出原因。 有时我把车开回来到维修车间,用小锤子敲发动机,观察爆震传感器PID和正时提前量PID。
