The defect
Blue Bird Body Company (Blue Bird) is recalling certain model year 2009-2015 All American rear engine non-school buses manufactured from June 23, 2010, through May 24, 2012, and equipped with certain Cummins Westport Model ISL G compressed natural gas engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
The risk
The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
