I just changed my clutch two days ago, and now i got my check engine light on.. I checked to see what code it was it is P0403. After doing some research i find out that a hose is pinched or the EGR valve is cracked etc.

I want to know does this make sense the reason for my car to be throwing this code and making this whistling sound is because it has something to do with this valve?

What do I need to do to fix this issue?

Thanks

 

chances are you pinched something when you pulled the trans so find out which one it was and replace...if its the egr buy a block off valve

 

whats a block off valve? and what does it do? will this fix the issue?

Sorry to ask so many questions but this is all new to me!

Thanks

 

bump for more imput

 

Check the vacuum lines under the intake manifold near the throttle body that go to the EGR. One probably came off when you were doing your clutch. Has happened several times on my Evo. I meant to zip tie them when the tranny was out and forgot.

 

Thanks for your imput man, i guess the EGR valve vaccum lines seem to be the common denominator...

I will look at it on Friday!

 

haha same thing happened to a friend yesterday..Most likely the vacum line under the TB popped off..Good times
There are 2 vacum lines that are ran behine the intake mani., they are held together with a clip, checlk and make sure both are connected to the correct nipples

 

i will let everyone know on Friday when i take it apart!

Thanks

 

fyi you should be able to just reach down and plug it back in..

 

as peteyturbo said, it was my car that had a vacuum line pop off. so far it seems to be the fix. going to do a boost leak check tomorrow hopefully just to double check everything

 

Same thing happend to me when I replaced my clutch last summer, I broke the egr control solenoid moving the t case out of the way.

 

I just got the P0401 code which is also related to the EGR setup...

I also get a "whistle" type sound when I let off the gas from time to time, or if I rev it in neutral, it'll whistle when I let off the gas and let the engine decelerate! I'm assuming this is related to the EGR hoses/parts.

I'm going to check the hoses when I get a chance!

 

thanks guys!
Im sure that happened to me as well when we moved the transfer case out of the way. If the EGR valve or solenoid is broken or faulty how much is for the part????

Once again thanks everyone.

 

bump

 

So i spend an hour trying to locate this issue and come up with nothing!
I cant see any vaccum line loose! i dont even know where else to look?

Does anyone have pictures of this EGR valve so i can work from?
