My 2000 2.5 has been tripping a P402 code (excessive EGR flow) for a while. I just decided to check into it and found out that the EGR valve diaphragm is bad, and it doesn't seem to get any vacuum anyway, so the valve doesn't open. I was able to supply enough vacuum to partially open the valve so I'm sure its normally closed. Is there something else that can cause this code?
