I have a 2008 Ford Escape Limited with about 110,000 miles on it.
Recently, the CEL turned on so I scanned for a code and got P402, Excessive EGR flow. I figured the EGR valve must be stuck, so I removed it and cleaned it, and verified that it would move freely.
Now I just get a P403 code, Exhaust Gas Recirculation Circuit Malfunction.

Not sure what else I need to check. Does anyone have any ideas?
I appreciate the help! I hate having to take a vehicle into the shop when I can just DIY.
