P04db CCV disconnect
Recently did a egr/def delete on a 2015 f250 6.7 upon completion on the second start up I received a check engine light code P04db, CCV is still connect and was not touched. Could this sensor failure be a complete coincidence or am I missing something here. Not sure if anybody else has come across similar problem.

Sounds like sensor failure. Normally I would refer you to your local dealer to have 17M04 performed if your truck qualified, however being that your truck is deleted and tuned, that is not going to work as part of the fix is a PCM reprogramming. Your going to have to replace it or live with the light.

Thanks for the response, I ordered a new sensor as I was assuming that was the case, just curious if anyone else had the problem immediately following a delete/tune .. im assuming it won’t be a electrical issue as nothing for the CCV was unplugged or messed with.
