When you have an issue with your mass air flow sensor, the airflow readings it provides will not be accurate. When problems arise with this piece of equipment, it can result in some troubling engine activity. The mass air flow sensor is between your car’s air filter and the intake manifold of the engine. The more power the engine uses, the higher the temperature rises. Most modern air flow sensors utilize a hot wire and a temperature gauge to monitor the temperature of the air around the wire. This measurement and information are essential for the engine’s control unit to monitor to ensure a balanced delivery of fuel mass into the engine.Īir density changes when temperature and pressure change, so the airflow rate fluctuates often when the engine runs.

It determines the mass flow rate of the air entering fuel-injected internal combustion engines.
