I have a theory. I ran a 2003 3500 across the state yeterday and it was acting up. pulled off to get fuel and got the codes off. It said P2509. Got back to the shop last night and plugged the scan tool in. it said P2509 and P0366. Now, just a thought, but would the fact that the bank 1 crank sensor is sending mixed signals to the ecm and that is what is causing P2509? I did some searches and couldnt really come up with anything close.
