Rescue-Ranger has been granted U.S. Patent No. 12,723,533 B1 by the United States Patent and Trademark Office (USPTO) for technology incorporated in its DEF head sensor simulator products. The patent, granted Sept. 1, covers technology designed to address diesel exhaust fluid (DEF) head sensor failures in diesel motorhomes, which can cause engine fault codes and progressive engine derating. Rescue-Ranger DEF Head Sensor Simulators provide simulated DEF sensor information to the vehicle’s electronic control system as an emergency tool, allowing owners to address immediate consequences while arranging proper diagnosis and repair. Based in Stillwater, Minnesota, the company is seeking partnerships with motorhome manufacturers, RV dealers, diesel service facilities and parts distributors.
