A guy I know had this issue and replace sensor but the new sensor was bad out of the box so he had to order another and it fixed it. If your sure your sensor is good, injectors are good and relief is good then check your wiring. Does it set code after sitting a while? Only when cold? Can you clear code after engine is running and keep code from coming back? I have read about a few trucks in the 11-12 model year with this issue and it ended up being an injector issue.
