You may need the shop manual for this.
Code 446 is a problem with the evap venting system, and code 453 is a problem with the gas tank pressure sensor.
The two problems may be connected.

These codes are for the fuel system the system performs a pressure test when the vehicle reaches a certain speed for a certain period of time, predetermined from the factory. The Gas cap is the most likely suspect. Disconnecting battery will reset (and delete) all error codes and clear the check engine light, VSC, etc. idiot lights on the dash.
Post further comments if further you have the same problem....
all of these problem codes refer to EGR valve and emission controls. It may be, if egr was fixed, it would be ok!! take off EGR valve and clean carbon from egr hole in engine and from EGR valve. if egr valve is bad or plugged with carbon then the car will act like it is not getting fuel, it will bog down.
