Man TGA EDC 7: EDC Error 3746 FMI 5 - EGR Actuator, Replacement & Recirculation Lever Check

Hello. I'm having trouble with Man. I am seeing the EDC error 3746 fmi: 5. So far, I have checked the EGR actuator, i.e. I replaced it with a new one because I had a replacement. I checked the installation from the EDC controller to the actuator. The installation is operational. The recirculation lever moves freely. What can I do more?

The error applies to the EGR air supply valve. On newer systems, the engine only has an EGR cylinder position sensor. The valve itself, and even two .... supply and proportional, are below, forward of the engine brake aperture elbow. Your error is with the supply valve, unless it has such a clamp on the coil. Typically electrical fault of the valve itself, or of the wires to it.

I felt that this applies to this valve one way or the other. I know what you are writing about, because I have covered the topic before. The problem is that I can't find these valves in this car. At this point, what you are saying should be just 2 valves. One higher and the other a little lower. And they are not here. Let me tell you that the EGR actuator power cord runs to the rear of the vehicle. There are 6 coils (solenoid valves) mounted between them, like an air distributor. And this is where the air comes from. This is a construction tractor, it has a Hydrodriva. Or maybe one of these coils does a problem, just tell which one?

So maybe you have an older system with a valve in the EGR engine itself. But you wrote that you mentioned him: /. Be sure of the leads to it, measure the resistance and leakage between the leads.
