I am getting a PO 223 code which means Idle validation to high. what does this mean for sure?

Shopkey says Bad APPS, bad ecm or wiring problem

3 of the 6 pins in the APPS connector are for idle validation. It's basically a single pole double throw switch, but in Chrysler's infinite wisdom, instead of using a basic switch for this, they made this part of the APPS from a WAD of circuitry. In idle position you should have continuity between pins #1 and #6 and any position OFF idle should have continuity between pins #1 and #2. Looking at the end of the connector that plugs into the APPS with the retainer clip on top, pin #1 is the top left, #2 is middle left, and #6 is top right.

I'm in the process of putting an APPS on my 12V I put in a '98+ 24V auto truck. I have wired a SPDT micro switch into and APPS to take the place of this circuitry. I have 2 APPS's that were replaced because they were bad and the idle validation circuit in both of them is what's bad.

I'll hopefully be able to let you know how it worked out this weekend.
