General letter of air leakage between Volvo S80, ECM_P228 122MAF sensor and throttle body?

Hello, if this kind of fault occurs, you can analyze it by reading the data stream. Read the specific value of our air flow meter first, and then read our previous opening reference and our engine speed to judge. Generally speaking, if there is air leakage behind the throttle, my engine will speed up when it is idling. He is an air flow meter, and the signal is still slightly weakened. I hope it helps you.
