When you suddenly get this code and message about 60 min till derate be sure 100% it's broken wire to DEFdozer.Remove fairing on passenger side,disconnect plug from the dozer, 30 inches to the left pull yellow tab all the way"UP"and disconnect "that BIG connector" with 15 pins.Now take a tester and check if the 2 wires from dozer to that big connector are good,not broken. Usually broken wire can be found 1 inch away from dozer.
Mine is OEM vovlo doser injector .. still got the code . Also check for the breakage on the wire (or short /touching the frame ). Frustrating when fixing the wire and brand new doser injector and after 2 month still getting this code . Also you need to perform the test with doser out and see if it s sprays like It supose to . It may ha e the right resistance , but if the ports are cloged, you'll still get faults. Mine just barely drips like a drope or 2 .
Also another tip is do a terminal tension pin drag test. Sometimes the terminals in the connector for the dosing valve spreads out and dont have a tight connection and then throws a code.They do sell just the pigtail connector so you don't have to replace the whole aftertreatment harness. Well atleast for a Cummins 6.7 ISB.

Good stuff , sir
Muy bien
thanks for your
Thank you
You're welcome
I check the resistance and was okay,but at the end come out to be bad douser valve
Thank you for infos, do you know what’s the voltage ?
Don’t worry about the voltage acm will sent the voltage that it needs at giving time.
Thank you.
