Fault code (P0069)

[Seb Van Ders]

Hi guys, So a short while back on my D5 euro 4 engine, a boost pressure sensor fault code came up (P0238) so i replaced the sensor. The code no longer comes up but now there’s a fault code P0069 (manifold absolute pressure - biometric pressure correlation). I’m confused to why this is happening. Does a new sensor need to be calibrated, or is there any cause or fix that i can do?
Cheers in advance👍

clean the map sensor then re scan

That was one of the first things I did. And I did in fact replace the MAP sensor with a Bosch one, so not no cheapo one. however problems are persisting and was even more in limp mode compared to the original MAP sensor. I just have no idea what the issue is. Cheers for your response though
