TOKYO (AP) — A sensor problem was found Sunday in one of the exchanged batteries on a Japan AirlinesBoeing787 jet, but it did not pose a safety risk, a Japanese broadcaster reported.

The Boeing Co. jets had been grounded for four months until their safety could be reconfirmed.

The problem emerged in a sensor that detects overheating in the modified version of the lithium-ion batteries used in the aircraft, NHK TV said. The batteries were encased to prevent overheating from spreading.

JAL offices were closed for the weekend, and officials were not immediately available for comment.

The Boeing 787 “Dreamliner” batteries overheated on planes that were in flight in Japan and parked at Boston’s Logan International Airport.

The 787s resumed commercial flights last month at JAL, All Nippon Airways and other airlines.
