P040D code
I really hope to find the answer to this. 2011 ram 6.7 bought the truck and it already had been deleted and has a tune(I have no idea what tune unfortunately). The issue that I'm having is the code P040D. I have tried to clear it and the only way is to disconnect the batteries but then the code will pop back up after a day or so. I can definitely feel and hear when the problem comes back before I even see the code after scanned. The truck feels sluggish almost like the E/B is engaged - takes more gas pedal to get her going - shift harder at times - when trying to accelerate it just kind of bogs instead of down shifting - if I stand at the front of the truck you can hear a rattling or kind of a knocking almost like a bad lifter sound more so on the passenger side. When I disconnect the batteries over night and start it, drive it. Everything is good no rattle, no code, no surging feeling while drive(happens while driving under light load - cruising). Drives like a dream.
I have read countless topics of others having this exact problem but haven't seen the one that has found the Holy Grail to the P040D code. I know there are diesel gods out there that this is a walk in the park for them. Please help......
