Hey folks, I'm back again with my basket case Cummins.
Previously, I ran into rail pressure issues, but now I have installed new injectors.
EGTs are way low, and rail pressure is almost spot-on, according to my Solus.
Previous codes were P0191 and P2BAC.
The issue I am running into now is a P21B2 code that keeps returning.
Before I go down the diag tree that lists just about anything being a cause, I wonder if I am missing something small or a procedure I missed with new injectors.
Trim codes were programmed, and the truck feels excellent, but the code was annoying, and I miss having a remote start.
Is any injector break-in procedure or relearning needed for other sensors or equipment?
