EGR DTC code> Need assistance	Sign In

Ok, I have two DTC codes, P0302 and P0401, I know what they are for but I can't afford a mechanic to fix them. From what i know the 302 is caused by the 401.....leading from there I have checked the feedback hoses, they are in good shape, not clogged....from there I changed the feedback sensor....I am not getting a 1408 code.....so this leads me to believe that it is the EGR Valve....just looking for confirmation........any ideas??

Single Mom :))

As a generic answer, the P0302 is a misfire on cylinder number 2. The P0401 is fir insufficient flow for the EGR. As Hammer Time stated, please post the year, make, model and engine size and we can help more.

Being way2old is why I need help from younger minds

You can easily test the EGR valve with a hand held vacuum pump. If it's not the DPFE then i would suspect a plugged passage in the intake. I doubt the misfire has anything to do with the EGR problem.
