Hey Guys,

I posted over in teh engines section but thought I would post here also.


I pulled a code 401 and I am replacing my EGR and DPFE sensor. I have searched the boards and cannot find the procedure to change these out. I currently do not have the service manuals and was wondering if someone could post the procedure to do this. Please help, truck is starting to run a little rough and I need to change these this afternoon when my parts are delivered.

Thanks

 

Just replace the dpfe sensor the egr valve rarely fails I have replaced lots of dpfe sensors and few egr valves 99% chance only the dpfe is bad

 

How do you get the trouble codes?

 

Lots of ways:

Buy a code reader ($300-400)

Go to a Dealer and let them read it ($40-100)

Go to AutoZone and let them read it (free)

Do it with your digital miliage counter (free)
