P0507 OBD-II: 怠速空气控制系统转速高于预期 OBD-II故障代码P0507是什么意思？
故障代码定义
See_also: P2317 OBD II故障代码 怠速控制系统的目的是管理发动机怠速，以满足发动机上不断变化的负荷，如空调、加热器鼓风机电机、雨刮器等的使用。
当怠速转速在一定时间内持续高于预先确定的转速水平时，代码P0507设定。
有此故障代码的车辆应送至修理厂进行诊断。 查找修理厂

怠速通常由安装在进气歧管节气门体上或节气门体附近的怠速空气控制电机控制。 在早期的车辆中，使用怠速空气步进阀或电机。 2000年以后，更多的车辆开始使用 "线控驱动系统"，即怠速空气系统被集成到电子节气门体的组件中。 使用上述任何系统时，都要注意提高或降低发动机怠速，动力总成控制模块（PCM）允许更多或更少的空气进入发动机。

当检查怠速空气控制故障的原因时，我首先查看冻结帧数据，以了解故障发生的时间。 我还通过转动方向盘来测试系统的基本功能，就像在停车时车辆停止，发动机怠速运转一样。 这将使系统通电并提高怠速转速，从而使发动机不工作。除了上述检查外，我还打开节气门体，查看节气门叶片是否清洁或充满积碳。
