Default Second IAC question

Still the ranger with the broken odometer, Idle stays around 1100-1200.
had a check engine light that gave me a P1506 code when a buddy checked and reset it. Accord to what Ive googled, thats a bad IAC valve, correct? But if I disconnect the wire from the valve, the truck idles normal around 700. I saw (also on the net ) that if you disconnect and the care idles normal, the IAC is working properly and the trucks computer is requiring a higher idle for some reason????
Want to make sure before I put out the cash for a new IAC.
Thanks again.
Go Steelers

That's an idle air control valve overspeed error. Means the IAC is overworking itself. Autozone has IAC's for $45.

Normally, I do too. However, they have a 2 year warranty on it, so let it fail.

The reason I bought the AZ one was because after my original IAC failed, I called the dealer because it was only a few days after I bought the truck. He sent me to his mechanic, who happened to be doing an oil change on a 2002 Ranger, that also belonged to the dealer. We swapped the IAC's for the hell of it, and it fixed my problem. However a month later the other IAC failed. So, I got suspicious that maybe my truck had something going on elsewhere that kept frying the IAC's. Instead of spending $80+ on a new Motorcraft IAC only for it to fry, I bought the cheaper IAC just in case. So far this one has held up.
