Here is more info

Thanks for the link. I just visually checked the system and discovered what must be the intake tube (short 90 degree rubber elbow pointing down) with its nose buried against/into an oil or transmission line.

It was at least 3/4 blocked by the oil line. I managed to twist it forward so its little snout is now clear. If this pump depends on free breathing, it was definitely not getting free air flow.

I have one more thing to check, then I'll reset the codes and drive around for a while.
