0482 - Jchism3406 - Today
I’m getting code 0482 pid 94 fmi 1 on a cm570. I’ve done replaced the check valves, fuel pressure regulators, a new filter and new screen inside the ifsm and a new pump. I did the 5 gallon bucket test and used a supply hose and ran it from there. The fuel pressure is 245 at idle. Soon as you hit the pedal and hold it open it’s drops down to 180 which is activating the code. Once you left off the pedal the code goes inactive. I also checked fuel pressure with a manual gauge and it still drops. What’s next. Any help would be greatly appreciated
