New! MFHU Replacement Sensors

For Bluebird buses equipped with new Diesel Exhaust Fluid (DEF) tank assemblies, these new MFHU (MULTI-FUNCTION HEAD UNIT) sensors fit Cummins diesel engines that are EPA/CARB certified, on highway applied, and built by Cummins on January 1, 2016 or later (Blue Bird production date January 18, 2016).

Blue Bird buses equipped with new (DEF) tank assemblies have a Gen 5 Tri-Function Sensor. The Gen 5 Tri-Function Sensor provides the level, concentration, and temperature of the (DEF) Diesel Exhaust Fluid in the reservoir and returns a defined CAN message for these values. The sensor and controller communicate on a “Private” J1939 data link with the Cummins ECM.

Grizzly’s commitment to quality is what sets their products apart from the competition. With the Grizzly replacement MFHU, you are guaranteed that the overall function of your engine will not suffer from a poor quality replacement.

We are happy to bring you these great new products.
