The recall affects Cummins Westport Model ISL G engines made between Sept. 12, 2007 through Feb. 2, 2014 and Cummins Westport Model ISX12 G engines made from Feb. 19, 2013 through Feb. 2, 2014.
The National Highway Traffic Safety Administration said Friday that condensation in the tubes that distribute air coming into the engine may freeze during cold weather. That ice could interfere with the proper operation of the pressure sensor, potentially increasing exhaust temperatures or causing flames from the exhaust pipe, which could burn a person or cause a fire.
No injuries have been reported.
