Sensor maintenance on the USS Enterprise-D
Sensor maintenance, or sensor maintenance room, was a room on Galaxy-class starships.
In 2364, Worf was in sensor maintenance while Geordi La Forge conducted routine maintenance on the sensor assemblies because the captain wanted his junior officers to "learn, learn, learn." (TNG: "Lonely Among Us")
Sensor maintenance was a partial redress of main engineering.
Although it is barely readable, sensor maintenance seems to be located on deck 14 room 2014.
