2003 bmw 745i with 4.4 motor codes 278e 2760 and 2761 where should I start to fix

I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
Thank you for your attention to the rating requirement.

278e - likely a bad pressure sensor in the intake air pipe

2760 and 2761 - likely a failed secondary air pump, problem with the air pump power supply, or clogged air passages in the engine

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
