Help me please

Hello I just recently bought a 2006 ford mustang, and it was doing good then the check engine light came on. So I used my OBD scanner and it says P0401 and code P2195 came up. So I did my research on these codes. I came to the conclusion that my EGR was bad so I replaced it. Few days go by CEL came back on. So I did more research and found that the MAP sensor also plays into effect with this code. So I replaced the MAP sensor. Another few days go by to today another CEL. The usual code P0401 came up and also a new code P2195. So I’m stuck I don’t know what else to check because vacuum lines look good and o2 sensor wires don’t look frayed. Please get back to me if you know anything

*UPDATE* check engine light went away. I don’t know why it went away while driving

sometimes it takes a few cycles for the DTC to clear itself

Did you just replace the parts? Or did you also do a code reset through the scanner?
