check engine light

Asked by kennyc Sep 03, 2009 at 07:38 PM about the 2009 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

My check engine light is on.  I am getting a P 0403 fault code.  Does any one know what that means?  Where can I get a list of what the fault codes mean?
I pulled the negative off the battery and the check engine light went out.  But I'm sure it will return

if you have a 5.7 engine the egr is usually faulty, the egr may still work properly but the electrical is shorted.
