Remove the valve and run the engine and see if it moves with the line attached?

Okay, when it was idling did you hear a loud exhaust leak, and a loud exhaust noise as well?

Okay, was there a loud hissing noise from a very large vacuum leak? Did the engine stumble and almost shut off?

If it did not then that passageway is blocked and that is why the code is setting.

Okay, sounds like the passages are clear.

Did you replace the EGR valve?

Hi, I replaced EGR but MIl is still on. Today I checked EGR hose and it was broken maybe it is a problem.

It sure can be. It will not allow the valve to open.
