OK, so long term solution will be to add wiring for both O2's to ground at their respective PCM pins. In the meantime, will this code prevent the car from going into closed loop?

I'm diagnosing an O2 sensor issue on my 92 Cutlass 3800 L67 swap, and have found something I either didn't notice when I initially did the wiring or thought it didn't matter and/or forgot about it....
