P2128 OBD-II：节气门/踏板位置传感器/开关 "E "电路高 OBD-II故障代码P2128是什么意思？
OBD-II代码P2128定义为节气门/踏板位置传感器/开关 "E "电路高电平。
电子节气门控制系统（ETCS）控制节气门的开度。 当驾驶员踩下加速踏板时，加速踏板位置传感器（APP）向发动机控制模块（PCM）发送信号，告诉PCM驾驶员要求从发动机获得多大的功率。 PCM然后命令节气门板相应地打开。 如果PCM检测到电子节气门位置传感器（APP）的信号，PCM将命令节气门板相应地打开。节气门控制未按要求工作，PCM 将设置代码 P2128。 PCM 还可能使发动机进入 "limp home 模式"，限制发动机的可用功率，以防止不必要的加速。
有此故障代码的车辆应送至修理厂进行诊断。 查找修理厂
