Engine

ODI #11428586

Incident: August 10, 2021 · Filed: August 10, 2021

DEF "Head" sensor failure resulting in power reduction to 5%. Due to faulty def head sensors the vehicle will experience power loss dropping to 5% load. These sensors do nothing but measure DEF fluid level and temperature in it's tank. DEF continues to be supplied to the exhaust meeting all EPA regulations in place at this time, BUT the Engine ECU will shut you down leaving you stranded. Problems with micro chip shortages have left many stranded with nothing in place to help them get "home".. We are talking weeks to Months in some cases only to have the def head finally replaced only to fail again with in a couple thousand miles. Emissions are not effected, but "Shaw Development" (DEF Head manufacturer ) Nor Cummins (engine manufacturer) has not done anything to prompt the EPA to allow a work around for this problem. Emergency Response vehicles do have programing in their ECU which allow them to operate normally until new parts are available. Why not for the thousands of Motor Home owners as well as over the road trucks which are effected as well. It's not a question of if this will happen, it's a question of when this will happen.
