Depending on your engine size, code 22 for your f350 is a map sensor concern. Map stands for manifold absolute presure. According to some of the fixes out there, replacement of this sensor takes care of the concern. With a scan tool attached you will see a 100-150 frequency.

if your using a generic code reader like from the local auto parts store, they won't retirieve powerstroke specific codes.

P1249 is wastegate control valve performance
P0475 is exhaust pressure control valve
P0603 is KAM (keep alive memory) error

Your truck has a back pressure valve that will close to aid in the warm up of the engine. Exhaust back pressure valve can stick and give the P0475. The P1249 might be related. If your disconnecting the battery to clear the codes that's where your getting the P0603. Your turbo need to come out and the back pressure valve ooked at..it's in the turbo pedestal.

changing your oil has nothing to do with a check engine light. a disconnect of the battery wont clear a code anymore.only way out is to have the code cleared with a scan tool which it will most likely come back on until you have the problem repaired

po603 is pcm keep alive memory error. either have pcm tested or replace pcm. because the pcm is at fault.

P0603 Internal Control Module Keep Alive Memory (KAM) Error

Ford dealer Tech said to check for corrosion on the battery terminals, if
they’re good the check each battery individually to see if all cells are good.
If that still doesn’t solve it, he says to start pin testing the computer ????!!!??

P0603 doesn’t always mean you have a problem, if you are running any kind
of chip, programmer ,etc. you will get that code.

Pull the filters and ck for plastic or o-ring in wrong place. Something is up in the filter. 

Bad glow plugs most probably or the glow plug controller. to check your glow plugs remove wire and check with ohm meter to ground. if they are working you should get a low ohm reading if one has a high ohm reading it is bad. if all injectors check good make sure your fuses are ok, also check and see if you hear the controller click when you turn the key to on. Does the wait to start light come on?

can I clear transmission code without a code reader/
