CEL code P04DB

FYI - Prior to the fix, I wasn’t able to find an answer to the code P04DB. Here is what my local Ford dealer was able to give me.
Note: It was last serviced by them, for turbo oil leak. Which was cover by my warrant at no charge. So they didn’t charge me for this second CEL visits. They owned up to why the CEL.

I hope this helps anyone else 🤓

Everyone seems to forget to click that hose fully back on. They must have removed the intake manifold for some reason.
