Disconnected IAC Air Assist Line and can't find where it belongs

[tsviatko]

It is the 3.4 gasoline (5vz-fe) engine.



You can see the hose in the red circle. I inadvertently disconnected it while pulling out the throttle body and now I cannot find what its far side is supposed to connect to. Where does it end on your trucks, guys?

Very difficult to see on mine as there are so many pipes in close proximity. My best guess is the one that terminates above cyl 6 spark plug on the base of the lower intake plenum. Hope this is not a duff steer.




Picture is of the back of the engine close to the firewall on the left bank of the V (left looking from inside the car)

Found this in the files too

Thanks a bunch for helping.

I am pretty sure it is not the cyl. 6 pipe though. I've removed the entire intake manifold. It seems the thing is going to 90904-13015 (http://www.japan-parts.eu/toyota/eu...0_/tool-engine-fuel/1708_vacuum-piping#17343H). That's about the only place left. I hope I got it right 90904-1

Its possibly the throttle body coolant hose, there should be two going to the throttle body one inlet and another outlet, its to warm the intake air in cold weather. to prevent the incoming air being to cold and not mixing so well with fuel.
