Very common code and I've yet to replace an EGR due to it. What you need to do is remove the throttle body and gasket. I'll bet that you'll see a lot of carbon built up pluging up the egr passage. Simply spray some carb cleaner on the carbon to soften it up and then clean it out with small point screw driver. Put it all back together, reset your pcm and you're goood to go.
