I just fixed this on my girlfriends 04 Galant. Remove the EGR valve, clean it with carb cleaner, put it back on and borrow auto zone's code reader and clear it. The check engine light won't come back on.

Remove the six bolts that hold on the plastic idiot-proofing..LOL. The EGR valve is on the back of the intake plenum. Carefully remove the attached vacuum hoses, noting where they went. The valve should be held on with two bolts. Remove these, and the valve should come off. Remove the old gasket. Make certain that the inlet where valve mounts is clean and free from carbon buildup. Either clean the valve or install a new one. Use a new gasket. Tighten bolts to 17/26 Nm. Reattach hoses, and you're off to the races...
