P0340克莱斯勒道奇公羊的故障代码经常出现在3.6L发动机上。 3.6L发动机使用四个凸轮轴和两个凸轮轴位置传感器(CMP)。 每个传感器都是双读设备,读取一个组上两个凸轮轴的位置。 PCM向每个CMP提供一个5伏参考信号和地线。 CMP为每个凸轮轴的进气和排气提供一个数字ON/OFF信号。PCM在指挥可变气门正时机构中使用的执行器后,使用该信息确认凸轮轴位置。 为了设置P0340代码,发动机必须运行5秒钟,并看到曲轴信号,但没有凸轮轴信号。 一旦P0340代码被设置,需要三次良好的CMP信号,以关闭检查发动机灯,并将代码移至历史代码存储。

首先,在IGN接通但发动机不运转的情况下,检查每个CMP传感器的5伏参考电压和地线。 传感器位于每个气门室盖的上端,最靠近发动机的变速器一侧。 电压读数应为4.5至5.02伏。 如果你没有看到这些电压,检查CMP连接器和PCM之间导线的完整性。

接下来,测量CMP连接器中电源电压端和接地端之间的电阻。 如果电阻为100Ω或更小,修复CMP电源电路中的对地短路。
