2005 Chrysler T&C EGR Issue?
 

I have a 2005 Town and Country that has a check engine light coming on and going off. I get access to a code scanner and the code that is throwing the MIL is P0406. The engine is a 3.3L. I know that the code means EGR Flow Sensor A - Circuit Input High, but can anyone tell me what the fix is to get the MIL to stop coming on. I pulled off te pipe from the EGR to the manifold and cleaned it but the issue is still there. Short of replacing the EGR is there another fix?
