Defect
Volvo Trucks North America (Volvo) is recalling certain model year 2013-2015 VNL trucks, and 2013-2014 VNM trucks equipped with certain Cummins Westport Model ISL G and ISX12 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. The recall began on April 12, 2014. Owners may contact Volvo at 1-800-528-6586. Volvo's number for this recall is RVXX1401.
