Crawl under and see if its connected. Those 2 codes would indicate its dead or disconnected.

Dead is a likely bet. When you replace it buy a direct fit sensor. Denso will work well and is not incredibly expensive at RockAuto, http://www.rockauto.com/

Before spending $$ check the fuse, its the EGR fuse and check that the brown ground wires on the back of the block are connected. They are right above the starter under the #4 intake runner. You can see them from above.
