How do you replace or clean an EGR valve?
The EGR valve is normally connected to the exhaust manifold. The EGR valve works by routing a small amount of the exhaust gases back into the combustion chamber. This helps reduce emissions of noxious gases to the atmosphere. You could try removing the EGR and then try to clean it inside with a rubber-friendly cleaner that is strong enough to break down carbon build up. Ask a car parts and accessories store for advice about the right type of stuff to use. Just an added note. I had a 1993 Honda Accord that was running very rough from 800 to 2500 RPM's. Almost like it was misfiring. The technician said the EGR valve was very dirty with evidence of carbon build-up. The problem continued after the EGR was cleaned and I had to clean out the 6 EGR ports. They had port access caps that had to be drilled out (on a Honda accord). The symptoms and repair were from the manufacturer's service bulletin. They are coat hanger size ports and were very clogged and the car runs great since cleaning the ports. I believe most cars have EGR ports tied to the EGR system. They tie the exhaust to intake airflow manifold for recirculation.

P0401 EGR flow problem on 2001 Honda Odyssey 3.5L?
P0401 indicates an insufficient flow of gases through the EGR system. While Honda EGR valves occassionally fail, your first step should be to check if the EGR is operating when vacuum is applied. If so, remove it and clean the orifice with brake cleaner. While you have it off, clean the intake porting with carb cleaner and a stiff wire brush. Carbon build up in either the EGR or the intake will set this code.

Operate the EGR valve manually if possible. If the engine doesn't stumble and die, the ports are likely plugged. Remove the valve and clean all of the ports. Check all vacuum lines, hoses, etc. for any damage.
