HELP! Can anyone tell me where this hose goes?!

Here's another diagram I found. Out of the three, hopefully one matches yours. In this diagram, the vacuum line in question comes out of #3 and is supposed to go to #2.

Thank you all for the advice! I was thinking it was an SAI related tube but thought otherwise because the component shown in the picture looks smaller than other pictures of SAI units I have seen. I will do some more digging around to see if I can find where the It might connect. Where is the EGR valve located in one of these?

I can't tell which line had the tape on it by just seeing the taped end? Where is the other end. Your codes are most likely from a vacuum leak because you have the hose disconnected.


Look through some posts like these for more pics of how the hoses go:

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.

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:
