Don't turn ignition off. Read the code while the light is illuminated.

Sounds odd but in this case it doesn't matter. The P code meaning is the same for any brand. The important things is that you've got the code.

I guess you need to remove the EGR valve, clean it and check again. If the code comes back you probably need to replace the valve.

I don't know anything about Civics sorry. You're better off Googling for some pics or videos.

Try changing your secondary waterpump, for the inverter, that throws up all sorts of warnings. Did mine and rund great, also check out parts for a Lexus,  cheaper than Alfie parts, £100 saved on the o2 sensor.
