That is the turbo underboost code. If you watch your boost gauge, you should notice that you are not getting normal boost pressures, even when you mash on it. There should be a considerable lack of power noticed as well. It's now time to clean/rebuild your turbo.
There are several write-ups/procedures on the site to prepare you to do it yourself. I did mine after it showed up on mine after owning the truck just 6-7 months. This is my first diesel and that is the first thing I did to it. It's a good reason to buy a few new tools if you are not already equipped, and a way to get to know your truck!
MPG and power increased considerably after I did it, as well as turbo whistle!
