I think you should pull the throttle body, it only takes a sec. Then use the test mode to get a better idea of what steps mean full open, full closed, etc. Negative steps would be on the other side of a home position, which would not make sense in this case. Since there is no encoder feedback on these, it must move all the way to one end first to get an idea of where it is... It does that when you key on. I think it will call that 0 steps, then go from there. Don't quote me on that, but i think that should be right.

Yeah, I am definitely going to take the TB off and run the valve test tomorrow.

So, on "key on" the number of steps, again lets say 160 for arguments sake, will bottom out the IAC. Now that it's closed and the car is on this position is considered "0" (I guess I quoted you anyways, haha) so then "open steps" could be 160... would that make closed 0? Because it takes 0 steps to close?
