Your code is a problem with your EGR system. The problem is your DPFE sensor. This sensor comes off your EGR tube and is connected by two flexible hoses. One is slightly bigger in diameter than the other.(the bigger one goes to the ref side). It also has an electrical connector on it. Replace it and that should fox youre problem.

I fixed it. The ports in the plenum were clogged.

Thanks

Did you remove the Plenum to clear the ports and if so was a gasket needed to reinstall?

Ok the problem is now fixed, but its not the plenum ports its simply the butterfly body ports, a 45 minute job and not the plenum, which would take a few hours.
