persistent EGR code p0440 850 1995

Hello. My T-5R has a persistent CEL from the EGR system. I've changed fuel caps, the filler neck is not in bad shape, all lines are connected. Where would I look next? Elbow connectors? Purge valve? Solenoid? Canister itself? Is there any trick I can try (cleaning something) before I go about replacing all these parts with other parts that may not fix the problem? Thanks much in advance!
