Keep getting the above error code on my P1s, and cannot find it on the Bambu Wiki.
It’s the hotend cooling fan. Make sure it’s plugged in correctly. Sometimes it looks correct but the connectors aren’t lined up.

It is the hot end fan. If it is not plugged in correctly you will get this error. It is sometimes really hard to tell if you have it correctly aligned, I would suggest that you unplug it completely and the reinstall it. If that does not work, come back and search this sight for the code. there have been a lot of post on it and many, many helpful suggestions…
New to the forum. I have gotten the same errors. The connector on the fan to the extruder board is terrible. How does everyone keep it plugged properly?
Do not disconnect it in the first place. 
If disconnected: good glasses, slow hands and a huge supply of patience.
