I have a 2022 Ram 2500 Laramie 6.7 Turbo Diesel and I got this code a few weeks ago: P218F --- Reductant No Flow Detected and I was told that it could be a few things that was causing it. I first checked the def injector and found it to be bad. Replaced it and the code was still present. Checked the pump and it wasn't turning on or pumping fluids so I Replaced that as well. The code is still there. I don't know which part of the wires to check for power with a multimeter. And I can't seem to find the fuse for the pump. So if anyone has had experience with this or has any ideas as to what I could do to fix this issue it would be greatly appreciated.
