Answer
if you have an egr code which one insufficient flow code is most common and is usually caused by bad dpfe sensor or clogged egr passage-their is ways to test this-apply vacuum to egr when truck is running if engine rpm changes more than likely dpfe sensor bad if rpm stays same or changes very little probably clogged passage this is not proper and 100 percent correct but most common method. if you don't understand what i am talking about take it to a shop if you do try that test.
