Do you need mass air flow sensor?
A mass airflow sensor (MAS) determines the mass of air entering a vehicle’s fuel injection engine, and passes that data to the Engine Control Unit, or ECU. The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine.
Where can I get a mass flow sensor for my car?
AutoZone makes finding the right mass flow sensor for your vehicle easy. Just select your vehicle’s year, make, model, and engine up above, and we’ll find a sensor that is made for your vehicle. We can even help you find any other parts you need to change it yourself.
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.
What happens if the mass air flow sensor is not working?
The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter, so that the ECU can adjust the amount of fuel getting into the engine. If the mass air flow sensor isn’t working properly then you will be faced with one or more symptoms such as lack of power and bad fuel economy.
Which is the best type of flow sensor?
Differential pressure flow sensors are the most popular type of flow sensors due to their performance and versatility. Commonly used in gaseous, low-flow, high-accuracy applications like semiconductor manufacturing, thermal mass flow sensors utilize a fluid’s thermal properties to measure the flow through a system.

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.
