P04DB error code

[Caleb Sousley]

Driving my truck home today and the CEL came on. It was the P04DB code:
(The engine control system has detected an improper connection/installation of the engine crankcase hoses)


When I was looking at the engine bay it looked like the dealership was messing around with my aftermarket COI during my oil change (looking for filter I assume) and didn’t put it back together properly.

Would that cause this error code to come up?
I cleared code after making sure all hoses were properly installed and will have to see if it comes back tomorrow.

Yah I guessed you'll have to wait and see. If it shows up again, take it back to the dealer and ask him again.

Hopefully I fixed it and won’t have to take it back
