I have a 2008 Dodge 6.7l Cummins. I just did the EFI live Autocal lite last week and now this week I have the P2453 code. This is the code for a pressure differential calling for a regen. What has everyone been doing with their Pressure sensors as far as plugging/unplugging the electrical connector and looping a piece of hose between the two air connections vs leaving them open? I now have a hard code that I can't clear. Thanks for the input.
