Yes, you are correct.
My understanding is that there are three failed sensors, not necessarily for the same reason.
We don't know that. There was
an inconclusive discussion over in Tech Log a few weeks ago - the consensus appears to be that there has so far been no information published on whether the removed sensor was found to be faulty on the bench or, if it was, what the precise nature of the problem was.
That, in itself, is very odd. If anyone knows more, please share.
The sensor was replaced before the penultimate flight and was ~20 degrres off for both flights according to the preliminary report.
The original replacement was due to intermittent problems that could have been the sensor or other things such as flaky connector.
