Schwarze Industries, Inc. (Schwarze) is recalling certain model year 2009 Schwarze M6000SE CNG-powered street sweepers, 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.
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.
Schwarze has notified the affected owners, and dealers will upload a new ECM calibration, free of charge. The recall began in July 2014. Owners may contact Schwarze customer service at 1-800-879-7933. Owners may also contact Cummins Inc. at 1-800-343-7357.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
