庆铃故障码发动机故障灯点亮！

您好，根据您车的故障分析，这种情况一般都是压差传感器本身损坏导致的问题。你需要先检测一下压差传感器本身到模块的三条线路电压是不是合适吧，如果线路电压都是合适的话，重点考虑压差传感器本身损坏导致的问题。

你好，目前车子是不是提速不起来呢？

不能全车扫描，你根据车型发动机信号以及国几的车重新进系统里面读故障代码发我看看

那你检测一下排气压差传感器本身以及三条线路电压对不对吧。

一条5付电源一条1.5到5付变化的信号一条搭铁

如果线路电压都是合适的话，直接更换压差传感器本身

拔掉检测

钥匙门打开

如果传感器合适的，线路通断或者模块本身都是有可能的。

传感器好坏检测电阻值数据

大于1.5欧

是的，这种情况基本就是压差传感器本身损坏或者线路电压不合适导致的问题。

中间的，是的

好的，如果电压合适，读下压差数据流也可以看看的。

电压不合适检查线路通断以及模块本身。

如果你需要百分之百包解决问题的话，也可以加我上面的企业微信的。

一条5付一条搭铁信号

发动机电脑版，

是的

电源电压对的。
