Emissions problem
I am showing a PO4DB(1/2) pending code on my 2016 super duty, I believe it is a emissions problem, my problem is I am leaving for Idaho in the morning from the San Francisco Bay Area, is it ok to drive for 700 miles ?

You should be able to make it with no trouble. When you get there you can take it to the dealer and have them replace the CCV that is bad. Ford has extended the warranty on the CCV. You might be able to put it together for the trip and clear the code.
The 6.7L diesel engine has a crankcase ventilation separator mounted on the driver side rocker cover, with a
tube connecting the separator to the fresh air inlet of the turbocharger. The tube on the separator side has a
tamper proof collar installed and is plastic welded to the separator. On the fresh air inlet side, a hall effect sensor
is present, to detect connection to the inlet casting assembly. The tube cannot be disconnected on the separator
side, and if it is disconnected from the inlet casting, a P04DB code is set, as sensor output drops below a
calibrated threshold. There are also circuit range checks, P04E2 and P04E3 to detect shorts to ground, or short
to battery/disconnected sensor, respectively.
