Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor. The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a fire or burn injury to a person near the exhaust pipe.
Cummins and Cummins Westport dealers will upload a new ECM calibration, free of charge, to remedy the problem.
The two companies began notifying the affected vehicle manufacturers on Feb. 14. The manufacturers have not yet provided a schedule for notifying vehicle owners.
For more information, call 1-800-343-7357. Cummins' number for this recall is C1462 for ISL G engines and C1461 for ISX12 G engines.
Cummins Westport is a 50-50 joint venture formed in 2001 between Cummins and Westport Innovations.
