What are the symptoms of a bad mass airflow sensor?
3 Signs of a Bad Mass Air Flow Sensor
- Stalling, jerking, or hesitation during acceleration.
- air fuel ratio is too rich.
- air fuel ratio is too lean.
What happens when a mass air flow sensor goes bad?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.
What kind of air flow sensor do I need for my MAF?
Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.
How is mass airflow sensor and oxygen sensor used?
Mass Airflow sensor and Oxygen Sensor are used together to control air/fuel ratio accurately in the engine. Mass Airflow Sensor-MAF sensor construction The figure-1 depicts position of Air Flow Sensor.
What’s the difference between Vane meter and MAF sensor?
It mentions Mass airflow sensor (MAF sensor) construction and working of Mass airflow sensor (MAF sensor). It mentions advantages and disadvantages of MAF sensor over Vane meter. Definition: The sensor used to determine mass flow rate of the air is known as mass airflow sensor.

What are the symptoms of a bad MAF sensor?
The symptoms of a bad mass air flow sensor include a car that is difficult to start, bad fuel economy, a rough idle, lack of power especially when accelerating and sometimes a fuel smell from the exhaust fumes. A properly functioning MAF sensor is vital for an engine to run efficiently.
How does a hot wire mass air flow sensor work?
Let’s see how it works. A hot-wire mass air flow sensor has a small electrically heated wire (hot wire). A temperature sensor installed close to the hot wire measures the temperature of the air near the hot wire. When the engine is idling, a small amount of air flows around the hot wire, so it takes a very low electric current to keep the wire hot.
