Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
I received these error codes for my 1998 Dodge Avenger, 6cyl. 2.5 What does these codes mean? Where would I start to fix these issues? ~THANK YOU ~ P0108 P1297 P0401
P0401 - EGR flow insufficient , P0402 EGR flow excessive
Easiest and cheapest(depending on where you live) is to go to a parts store and look in a Haynes manual for your make and model vehicle

p0401 is lack of egr flow p0171 is bank 1 lean So we have two problems that are commonly related, often accompanied by high idle that will not return to normal. With out high idle problem you may have a pluged EGR or Vacume leak at the EGR system. THe High idle is definately a clue that you have leak in the EGR system.
