CID 0091 FMI 03
产生此代码的情况:
电子控制模块（ECM）可检测以下状况：
- ECM 已通电至少 3 秒。
- 油门位置的信号电压高于为此应用场合设定的诊断上限。
- 油门传感器的电源在预期范围内。
系统响应:
控制面板显示屏会出现一条警告。 如果发动机正在运行，则 ECM 记录该诊断代码。 该诊断代码可在通过电子维修工具查看。 ECM 将使发动机返回低怠速。
在清除故障之前，ECM 忽略油门输入。
在将钥匙开关转至 断开 位置，然后在返回至 接通 位置之前，ECM 也会忽略油门输入。
发动机将默认为故障缓行回程模式。
来自油门位置传感器的信号电压过高。
测试步骤 1. 进行以下的诊断步骤: 数字油门位置传感器回路 - 测试
结果:
- 正常 - 停止
