If we can hear the noise it would help us know what is wrong, please upload a short video of the noise from under the hood.
P0301 - Cylinder 1 Misfire Detected
P0480 - Cooling Fan 1 Control Circuit Malfunction
P0300 - Random/Multiple Cylinder Misfire Detected
U0401 - Invalid Data Received From ECM/PCM
So it looks like you may have two problems, engine misfires and a cooling fan that is not working, can I ask if the engine overheated? If so this can cause the engine to misfire. Also, I have seen these engine need timing chain guides or camshaft actuators but this will depend on the noise, that's why I need the video. Also, can I ask when spark plugs and ignition coils have been replaced?
