Defect description
PACCAR Inc, is recalling certain model year 2014-2015 Kenworth T440, T660, T800, and W900 tractor trailers manufactured January 23, 2013, through February 4, 2014, and certain model year 2014-2015 Peterbilt 320, 365, 382, 384 tractor trailers manufactured January 21, 2013, through February 5, 2014, and 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.
Manufacturer remedy
PACCAR will notify 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 PACCAR at 1-425-468-7400. Paccar's recall numbers associated with this campaign are 14KWG (Kenworth), and 214-C (Peterbilt).
