lildisco Posted June 19, 2017 Report Share Posted June 19, 2017 P04DB - CRANKCASE VENTILATION SYSTEM DISCONNECTED Quote Link to comment Share on other sites More sharing options...
Dehcure82 Posted June 19, 2017 Author Report Share Posted June 19, 2017 I've checked all hoses but everything is intact nothing is disconnected. I need a diagram of the ventilator but can't seem to find it. Quote Link to comment Share on other sites More sharing options...
lildisco Posted June 19, 2017 Report Share Posted June 19, 2017 If you're not modded, you should be under warranty, just take it to the dealer 1 Quote Link to comment Share on other sites More sharing options...
Dehcure82 Posted June 19, 2017 Author Report Share Posted June 19, 2017 I am modded but I just re flashed to stock and the code didn't come back on hopefully it stays that way, if it does I will have to schedule an appointment with the dealer and see what happens.

Dehcure82 Posted June 21, 2017 Author Report Share Posted June 21, 2017 I don't know but I had to clear the code prior to re flash but since I've yet to get the code again 1 Quote Link to comment Share on other sites More sharing options...
junehhan Posted June 24, 2017 Report Share Posted June 24, 2017 I cannot remember, but doesn't a tune run a little more boost? I wonder if a pressure spike caused some sort of freak condition. 2 Quote Link to comment Share on other sites More sharing options...
Dehcure82 Posted June 26, 2017 Author Report Share Posted June 26, 2017 I don't know what happened but I didn't get a cel since the re flash. I don't know if it has anything to do with it but I recently ordered a catch can. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 26, 2017 Report Share Posted June 26, 2017 Is there a sensor on the clean side PCV line? Maybe it's seeing some action it's not supposed to? Worth a check and clean. 2 Quote Link to comment Share on other sites More sharing options...
Dehcure82 Posted June 26, 2017 Author Report Share Posted June 26, 2017 I'm not sure but I will definitely check and clean if possible. Thanks 1 Quote Link to comment Share on other sites More sharing options...
