The defect

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.
The remedy
Cummins and Cummins Westport has notified owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Customers may contact Blue Bird at 1-478-822-2242 or Cummins Inc. at 1-800-343-7357. Blue Bird's number for this recall is R14XB.
