How does a mechanic diagnose the P2229 code?

A mechanic may begin diagnosing this trouble code by ensuring that the engine is running properly. If this trouble code is associated with any misfire codes, exhaust codes, or emissions codes, those issues should be resolved first. Next, the mechanic would locate the barometric pressure, mass airflow, manifold absolute pressure, and throttle position sensors and test them all according to the manufacturer’s procedure. During these tests, the mechanic would confirm the integrity of all the circuitry associated with this system. Finally, the powertrain control module would be tested. Depending on the results of these tests, the mechanic would then make a recommendation to the customer as to which part would make the most sense to replace.

Patrick was beyond anything I could've expected. This was my first time using your mechanic. Patrick was 15 minutes early, which was amazing. I was caught in a little bit of traffic, but he did not mind patiently waiting. When I got there, he was pleasant, knowledgeable, and listened to my concerns. Patrick did a full and thorough investigation on my car and its issues. He did not mind explaining what I did not understand multiple times and was very easy to talk to. Thank you again Patrick, keep up the great work!
