Making Sense Of Your Mass Airflow Sensor
Our Check Engine Light Diagnostics Experts Are Here to Explain
What Is A Mass Airflow Sensor?
Each and every component of your vehicle’s engine plays a pivotal role in its power and performance, including the mass airflow sensor. Also known as an MAF sensor, this part of your engine is located between the intake manifold and the air filter. It is responsible for calculating the proper amount of fuel needed for optimal air-fuel ratio, or AFR. The mass airflow sensor has two sensing wires, including one that is heated by an electrical current and one that isn’t. As air moves along the heated wire, it will cool down. When the temperature difference between the two wires changes, your vehicle’s mass airflow sensor will automatically adjust the current to the heated wire. This electrical current is charged to a voltage or frequency sent to your car’s engine control units, or ECU. The ECU will then interpret this as airflow and adjust the amount of air entering your engine accordingly. If your mass airflow sensor is worn out or faulty, it can affect the overall drivability of your car.
Is Your Mass Airflow Sensor Failing?
If your mass airflow sensor fails, you will notice some telltale warning indicators. The most common signs of a bad MAF sensor include an illuminated check engine light (CEL) on your dashboard, jerky driving, engine misfires, rough idling, excessive black exhaust smoke, your car struggling to start or stalling, and poor fuel efficiency.
