help with check engine light

SID 5 is the #5 injector circuit. I have no listing for an FMI of 0 with that SID though. FMI 0 is data valid, but out of range high, which I've never seen on an injector circuit.

Sounds to me like you may have a bad injector or a wiring problem.

 

I own a 2009 freightliner columbia with the dpf system my check engine had turned on I ran it with the computer temperature was getting too high on the dpf filter so I bought a new one they run about $820-840 but you got to return the old core or its twice the money. It also has a D O C filter that goes in front of the dpf filter that one is worth about $1650 what I did I sent that one to get it cleaned out only thing I didnt do is change the sensors two of them go one on your dpf other on D O C theyre like 70 each. Im going to have to change them my check engine light came on again lol well im on the road im assuming its cause of that
