The other end of the taped hose is the one that is circled and attached. The taped end is the disconnected hose from the attached other circle which is most likely the SAI unit. 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.
