P0420 relates to the catalytic converter. The computer sees little or no improvement in the exhaust before and after going through the converter. Either your oxygen sensors need replacement (3 total) or you need a new catalytic converter.
What is the mileage on the vehicle? Does it run well? Oxygen sensors generally start to fail after 70,000 miles. Catalytic converters usually fail because the engine is runnig rich and the owner ignores that fault for months. This causes the catalytic converter to overheat and fail.
P1456 relates to the evaporative emission system. This system holds the gas fumes in the system so they are not vented to the atmosphere. The most common cause of this code being set is failing to properly tighten the gas cap after refueling. Take the cap off and clean the sealing O-ring. Put it back on and tighten till it clicks 3 times. Make sure you have the correct gray colored gas cap. Clear the code and see if it resets within a few days. If it does, try replacing the gas cap.

SOURCE: Check engine and d4 lights on
d4 is flashing as a trouble code for the automatic transmission... i would say without research that it is a code for a transmission solenoid. maybe while washing the car some water got in and caused a short...these solenoids are usually weatherproof....you could try disconnscting the battery for 30 secs..to clear the trouble code and then start the car. remember you may lose your preset info!

Maybe the solution
There is a recall on the ignition switch,
My 99 Ody with 120K would suddenly switch off and come back while runing, Take it to dealer and report to Honda, Since out of warranty. The dealer would do the repairs estimated at $100 charge to you.

It sounds like the timing belt is off a tooth. Did you have it scanned to see what code was in the computer? These engines will surge when the cam timing is off.
