There has been no mention of an AOA failure prior to its replacement on the evening prior to the crash. It was apparently replaced as trouble-shooting in response to repeated write-ups of Capt unreliable airspeed & altitude. This did not correct the unreliable airspeed & altitude, but rather introduced an additional failure on the last two flights.
