Ice May Form in Intake Manifold

Eldorado National-California, Inc. (Eldorado) is recalling certain model year 2007-2014 Axess transit buses, 2008-2014 E-Z Rider II transit buses, and 2008-2012 XHF transit buses, equipped with certain Cummins Westport Model ISL G or 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.
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.
