Thread: IAC motor has unwound itself and won't go back in.

  1. #1 Guest

    Default IAC motor has unwound itself and won't go back in.

    I had the IAC motor out of the throttle body, but was connected to the wiring harness. The ECU send a command to close the IAC, and since the unit wasn't contained, the plunger just kept going and completely ejected itself from the IAC motor. Now the IAC motor does not seem to work. Is there some way to reset it, or zero it out, or some way to command it to pull the plunger all the way in? Or do I just buy a new one? Thanks, Andy.

    There is a way to reassemble it, but some people have trouble with it afterwards.
    I'd just replace it:
