NYT
article as of today is the first I have seen:
After the crash, the replaced angle of attack sensor was shipped to Minnesota, home of Rosemount Aerospace, the Boeing subcontractor that made it, Mr. Nurcahyo said. He and other Indonesian investigators went to Minneapolis in December. The sensor, he said, was deemed defective.
No more details and that is the only report, Indonesian leak, maybe a pinch of salt needed.
Also doesn't explain how a defective sensor was replaced and still the a/c is getting dud data on that side. Either there are a whole batch of defective sensors out there (so we should be seeing failure on NGs as well) or there were two problems co-occurring.
