I have a 2006 evo 9, can anybody tell me the location of the EGR valve?

 

Under/behind the throttle body on the back of the engine.

This should help you. Check the vac hose first.

Thanks, thats was very helpfull.

 

I had a vac hose pop off of mine and it ran like poo until I got it back on. Was a very fast fix.

Hopefully that is all it is for you as well.

It seems a lot of people ziptie the things back on.

 

Here is another link it might help a bit more.

there you go

 

Zip-tie every vac line you can get your hands on back there....

 

hopefully the egr port isn't clogged... seen that cause the code p0401 b4 too

 

Sometimes it's the EGR Solenoid that's causing the problem.

 

Thank you guys for all the great help. I found it and fix it. it was just one of the hoses that it was loose.

 

I had the same code p0401 pop up, verified with evoscan and it said it was insufficient egr flow. A quick check around the vacuum lines and i found the hose for the egr valve hanging loose. im happy again, one more day w/o the SES light!

 

I have the same code...do you have to drive it around to get the light to turn off or should it turn off as soon as you get the vacuum line hooked up

 

I am once again reminded of how helpful this forum can be. I recently had the "Service Engine Soon" light come on in my original owner, stock 2003 EVO VIII. I took it to my local Auto Zone to have the code read; P0401 EGR related. I get back home, search P0401 on the evolutionm website, and find the common problem of the vacuum hose to the EGR valve coming off. I go to the car, reach under the throttle body, and sure enough the vacuum hose is off. I put it back on, reset the SES light, and it am good to go. Thanks to all that take the time to share their experiences and knowledge!
