I hope this helps someone but I had exactly the same problem for nearly eight months....then one day I serviced my 2.2 CX5 myself and found the small hose below the main air intake pipe on the air filter housing was not connected, it looks like a return breather hose. Once reconnected and driven a few miles fault has gone. I had Air mass metre fault and scbs fault. Now completely gone and all for a tiny push on pipe.
