error p0401, EGR probs


  

aras420 -> error p0401, EGR probs (5/8/2008 12:17:13 PM)

Well, got my light checked at autozone for free... p0401 is the code "EGR flow insufficient"   Hmmmmmmm....  is it the solenoid? A mech at sts said they go bad on the 2003 eclipse gt often.  Could it be anything else before I go dumping money on the part(s)?  Also is there a way to check the solenoid to see if that is the problem?


If I am correct it is the black cylindrical thing in front of the egr valve to the right (towards drivers side) of the manifold?  It is making a swishing sound about twice a second when the engine is idling.  Is this normal?

Car seems to be running fine but, I hate that light...  I want it to go away.  I have a AEM cold air in it and that's about it beside some nice rotors.  The light came on a few months after I put the CAI on so, I don't think that's what caused it.

Any help is appreciated as I am too broke to pay for repairs or replace the whole EGR system.

Did a quick google search on your code and came up with this. Lots of things to try, a lot of which are free but time consuming. Hope this helps:
