If you connect the green connector in the engine bay, that will bring up any stored codes.

Once you've read the codes, I've got a manual here. If you post the codes that you read, I'll look 'em up for you.

By not giving the answer directly, I was encouraging a little bit of research with the resources given.
All the answers are in that link

First: the code refers to the EGR solenoid Not the valve or it's plumbing. The solenoids have a tendency to go open electricly.
Fixing hoses or valves will have no effect on the code.
Second:, disconnecting the battery will not clear codes stored in the ECU, it will only reset the ECU's "learn mode"
To clear the codes both sets of connectors --
the "test mode" connectors (green)
the "read memory" connectors (black sometimes white) -(BTW these are the ones you must connect to get stored codes).
and then turn the key to run
You must fix the problem for it to be erased, that much was correct.
Here is another link you should read

Turn the key, engine off.
Connect only the white (or black) connectors.
Turn the key on, engine off.
Record the stored code(s).
Turn key, engine off again.
Disconnect the white (or black) connectors.
Connect the green connectors.
Turn the key on, engine off.
Record the code(s).
If you get a code under both test procedures look at the unit detailed in the code list.
If you get a code with the white (or black) but not with the green ones, it's in the wireing harness connected between the unit and the ECU, or the ECU.
I didn't read the second link, this info may be included there.
