P0400 code

Manual says this is an EGR valve flow malfunction. How do I confirm? Is this a vacuum test or do I blow air into it and determine if clogged? Thanks

Poor advice. Dont listen to this person.

You should be able to visually see if it is blocked or not.

It's been a while so i'll and i'm going by memory but if you pinch the vacuum hose near the throttle body (yellow dotted tracer)- it should INSTANTLY stall your vehicle or make it run rough.
