Danisand, Error code P2228 is Barometric Pressure Sensor A Circuit Low and P2004 is Variable Tumble Shutter Valve Stuck Open
Possible causes
- Faulty VTC Shutter valve actuator (Stuck open)
- Missconnecting or pull out the vacuum hose
- Faulty Variable tumble solenoid valve
- Variable tumble solenoid valve harness is open or shorted
- Variable tumble solenoid valve circuit poor electrical connection
from here. Check your vacuum lines as well as your EGR valve.

p2228 is a intake sensor error so you may have a plugged air filter or a broken MAP sensor .the p2004 is a intake manifold leak probably a vaccum hose around the intake
