P0402 code another question

Ok like the title says, Advanced Auto Parts diagnosis is P0402 exhaust gas recirculating Excessive flow. I replaced my egr valve, based on everything I've read, during the replace I didn't see any lines that needed to be replaced or any lines that had come off. CEL light is still on. Took the throttle body off and gave it a cleaning. Any precise guesses or should I just go ahead and buy the vsv and replace it. If that's what is suggested does anyone have the part number maybe from Amazon or a parts store. Thanks in advance.

 

Following. Same issue here.

 

Also when I changed my egr valve there was what I can only guess was coolant in one of the lines, one of the larger lines coming off the egr vavle and goes under the throttle bottle. Would this be normal? It wasn't a lot but still not sure if it's normal.
