Why does the engine light keep coming on indicating EGR valve in a 2000 Chevy impala after the EGR valve was replaced?

I just replaced my egr valve and my light went off, however some reasons for yours not to go off might be that the hose/pipe coming out to the eghaust manifold into the egr valve has enough deposits in it to cause a blockage.....signifying that your old egr valve was good, just not getting any unburned fuel to it. I don't know how to clean the blockage out so maybe search the net and see if you can find out how to do that. perhaps a carborator cleaner will work?
