If the intake air quality is good, the ECU will allow the engine to work properly. If there is any contamination in the air, the ECU will act upon it by sending a signal to the vehicle’s engine management system that it is not getting the It’s very important to have your mass air flow sensor cleaned regularly, usually at least once a year.
