Hello,
The code
P04DB - Crankcase Ventilation System Disconnected
It can get triggered due to a few different reasons.
It could be due to the disconnected hose from the crankcase to one side of the crankcase pressure sensor, disconnected hose from the intake manifold to the pressure sensor, damaged PCV hose O-ring seal, disconnected vacuum lines. It can also get triggered due to an incorrectly installed oil cap.
I have attached the trouble shooting guide for the code below. Follow those steps as it can help you determine the issue.
Let me know of any questions.
Thank you.
