Thanks for the advice. Unfortunately, the best source document I have is the haynes manual. There is a procedure in the haynes for checking the voltage on the harness to the IACV. I will check the voltages as well as check the resistances of the IACV tomorrow once there is sunlight.
I also just purchased a used IACV for $45 as insurance.
I feel like the wire continuity procedure might be a little out of my league. Thanks again for all the help.
EDIT: Just found an online copy of the ESM. Link for others with similar issues:

I see the mention of the power steering air control valve and I am reviewing the troubleshooting procedure.
