From the other posts below it seems like the taped end will lead to the EGR valve. However, I do not know where the EGR valve is located in relation to the rest of the engine. Hopefully, once I attach the hose those codes will go away! Just gotta find that connection first.
These engines use a secondary air injection system (SAI) which blows outside air into the exhaust . They do NOT have an Exhaust Gas Recirculation valve (EGR). We have pics of the SAI system posted in a variety of poses for you, but here's one more if it helps. Most of it is located on the right side of the engine under the intake manifold:
