Defect
Oshkosh Corporation (Oshkosh) is recalling certain model year 2012-2014 S-Series Ready Mixed Concrete trucks manufactured February 29, 2012, through January 27, 2014, and equipped with certain Cummins Westport Model ISL G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
Safety 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.
Remedy
Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. Cummins Inc. and Cummins Westport Inc. began notifying the affected vehicle owners in April 2014. Owners may contact Oshkosh at 1-920-235-9150 or contact Cummins Inc. at 1-800-343-7357.
