Question about Ford F-250
SOURCE: egr problem
Lets tackle the EGR code first. Your vehicle is equipped with an electronic EGR valve, and the code is referring to an error with the pintle position. Your first port of call is to go back to whoever read the codes out and have them reset using this procedure:-
Switch off the ignition
Disconnect the wiring plug from the EGR valve
Connect the scanner
Switch on the ignition
Clear the code using the scanner.
Now this bit is VERY important:- As soon as the scanner tells you the codes are cleared, and I mean that very SECOND, switch off the ignition IMMEDIATELY, or the code will reappear.
You can then disconnect the scanner, reconnect the EGR valve, and then turn on the ignition.
If the code comes back then remove the valve and clean it, and whilst the valve is off, you may as well take the opportunity to clean out the ports where the valve was sat.
If that fails then its a new EGR valve I'm afraid!
Now for the other code, and I'm afraid that unless you have a proper scanner which gives live data then all you can really do is check the wiring for the crank sensor and then if that checks out ok then fit another sensor and see if that clears the code.
Very best regards

yes it is..you need to replace egr valve assembly..make sure you disconnect battery while replacing..some times fault will return even after replacing valve..

vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

Or before shelling out that kind of cash; you could try cleaning the seal on your gas cap and/or replacing your gas cap first. My '06 has tripped this code twice (after very dry or very cold weather).

Turbocharger (TC)/supercharger (SC) boost pressure
control B - electrical malfunction
probable cause of it might be
Wiring, TC/SC boost control solenoid
but it could differ from auto maker

sorry but your code reader is not reading manufacturers codes ,if an american market vehicle then you should be able to read them but if this is a europeon model then how did you manage to get this code??
P0235....Turbo/Super Charger Boost Sensor 'A' Circuit
this is a generic code if its any help
