The DTC P0272 was thrown on my duramax I believe it’s a balance issue or something like that. The code is something to do with the voltage for the injector being to high or to low. So I had the injector replaced and the light is still on and nothing has changed anyone know where to start looking? Or has anyone had this problem. My guess is it’s a electrical problem because the truck is running fine. Also the truck is tuned and deleted

I'm also dealing with this code but it is intermittent. I've noticed when the issue is present, my battery voltage drops. I'm going to start inspecting wire harnesses and plugs. Let me know if you find anything.
