What is the fmi on that code? 5 or 7? Could be that it needs the new style pins in the harness.

+1 on what Steeler said. Also , there is another bulletin on injectior fault code due to the engine brake malfunctioning. I believe it’s only on the MP7 that this would happen on. The FMI is key in determining what to do next

FMI 3 or 5 could be the harness end as Steeler said . FMI 7  with miss or running rough could be oil control valve stuck open or stuck engine brake plunger on rocker arm 

Good catch. I should have said fmi 3 or 5. Not 7. Thanks.

if you are replacing injector make sure to program new injector trim codes/files.

you will need ptt program to do that.

also, injector cups are common issue on those
