Measuring ohms makes no sense, ABS sensors can only be measured with an oscilloscope.

If you have unplugged the old ABS sensor and plugged the new one in correctly, it should work.

Normally the sensors need to travel a few meters to register with the car and for the ABS error to go away.

If this doesn't happen, either the new ABS sensor is defective or you have damaged the cable.

Thanks for your help. The vehicle has been driven for miles already during testing.
The diagnostic codes indicate both sides throwing codes and the sensors come as part of the new MOOG hub assy so I find it hard to believe that both sides would be faulty.
Also, as diagnostic test, we unplugged the MOOG sensor and plugged the old one back in...the ABS light didn't clear. However, it is true that we did not drive it to see if it would clear at that point because we didn't want to have to do all the parts off and on, etc. until we could fully test other things first.

We need to clear the codes and run a live diagnostics test while driving again, which we will probably do tomorrow. And other things y'all have mentioned. With all the other work done, my hubby can barely move from pain, as he has back issues. But we will live to tell another day. ;-)

Update: we discovered that the dust covers were put on backwards and possibly putting pressure on the sensor, which would cause it not to read correctly. Pulling everything off to fix that first to see if that might be causing the issue. Then going from there...

Final update: fixed dust cover placement and that solved the issue. Placement was putting pressure on the sensor so it wasn't seating correctly. We did have to replace one of the sensors because it was likely damaged during this process. Put old sensor on and solved the problem. We'll get another new MOOG sensor so we have all new parts.
Lesson learned: make sure to put the dust covers on facing the correct way. ;-D
