Hello I have a Nissan Maxima and a "service engine soon" light is ON, on my gauges. The code reads as P0400, "EGR Air Flow Malfunction." I was wondering if anyone can tell me where under the hood can I look and find the EGR valve. I would prefer to see some pictures as well on where exactly it is, if possible. Thank you very much

 

Right under the throttle body, looks like this:



I would take a good pic for you, but my car doesn't have EGR. Hopefully this works for ya ^^

 

Here's a slideshow of EGR tube pictures from my 99 model. The 2000 model will be similar. Usually a clogged EGR tube causes the CEL code P0400 to appear.

Note: I've never had to cut any bolts or tools to remove or replace any EGR component.

The actual EGR valve is in the following picture.

 

Is it at the bottom? Or would I have to remove any other parts to reach the egr valve? Sorry I look at the pictures and then check under my car's hood and I'm having trouble finding it still

 

Here is a pic from under the car,

Remove the airbox and all the other crap up to the tb....like D.Stillwell it's below the throttle body...

What year is your max?

 

The year 2000 is my car

 

did you find it?

 

Here's a video from a 2000 model. The EGR part starts at 2:30 into the video.

Oh okay, I got it now. Thank you all for the information. I should work on the EGR Valve pretty soon. Happy Thanksgiving to all & God bless you
