Exclamation P0505 After Timing Belt and Valve Job

Hey guys, I was hoping you could help me out. Awhile back I did he knock sensor relocate to pass emissions, and this worked fine. Well my timing belt went early on me (although I should have replaced it) and I needed a timing belt and valve job. I did the water pump, head gasket etc. while doing the other work. So I get my Xterra back from the shop and it now has two P0505 codes. So I am assuming its an issue with the IAC. My question is this, it looks like my mechanic did not plug in the harness that I tapped into for the knock sensor relocate, but is the harness for the IAC also in that group? I spliced into the harness where it first splits on top of the engine bay and I could have sworn there was another group of wires in there that I did not touch. Any help would be greatly appreciated. Thanks

Go to the DIY section and look at the pics. It may identify the wires more clearly.

Yes, the IACV is located on the same 8-pin connector as the Knock Sensor; the black one on the right.
