Cummins 6.7 Injector Codes?
2014 RAM 6.7 - About a month ago I got a P020D code (#4 cylinder, possibly bad injector). Cleared to the code and hasn't come back. A few days ago, another CEL. P020B, cylinder no. 2, same thing....

How many miles? Lots of people have 150-200K miles on stock injectors with the 6.7. Its possible to have 1 bad one, but 2? Unless you are up there in miles, I would suspect the injectors are fine or you just have bad luck. The fact that something happened to cause #4 injector to throw a code, but it didn't come back makes me think its not the injector, but something else.
I would start by making sure all your wiring harnesses are in good shape and securely fastened. I'm guessing that something is loose in the injector wiring harness that is causing a voltage drop somewhere that is causing the code. The wiring harness is the first place I would look.
At a bare minimum I would say you need further diagnosis. Good luck!
Thanks for the reply! I'll see if I can figure out how to look at the wiring harness...
It has 128k miles.
