June 2 (Bloomberg) -- A problem with an air-pressure sensor on a battery container in a Japan Airlines Co. 787 Dreamliner made by Boeing Co. caused the airline to use another plane for a Tokyo-to-Beijing flight, according to Kyodo News.

Japan Airlines said the sensor showed a difference in air pressure between the outside and inside of the container during a safety check before the departure of Flight 21 from Tokyo’s Haneda airport, the news network reported.

Yesterday, Japan Airlines and ANA Holdings Inc. restarted Dreamliner flights. The twin-engine jetliner, the first built chiefly of composite materials, was grounded for more than four months because of battery malfunctions.

Susan Bradley, a spokeswoman for Chicago-based Boeing, said that the company was aware of the issue and was working on it with the airline. She referred inquiries to Japan Airlines.
