About

Mass Air Flow Sensor

Put a stop to engine hiccups and stabilize your engine’s air-fuel mixture with a new mass air flow sensor (MAF) from AutoZone. We carry great brands like ACDelco, Bosch, Duralast, Hitachi, and more. Buy your new air sensor on AutoZone.com for free next day delivery or pick up your parts in an AutoZone auto parts store near you today.

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. If you’re experiencing bad MAF sensor symptoms, AutoZone is the one stop shop for all the replacement parts you need.

Cars can have either an analog or digital mass air flow sensor. Analog MAF sensors produce a variable voltage output, whereas digital sensors send a frequency output. Both outputs are sent to the engine control module to regulate air-fuel mixture and the automatic transmission system. Regardless of the type of MAF, the sensors work similarly.

The sensor, located between the air filter and the intake manifold, contains a hot wire and a temperature sensor. The hot wire is heated with an electrical current. As your vehicle accelerates, the throttle opens, allowing the air that enters the engine to pass through the MAF. The air cools the wire, so as more air passes through the MAF, more current is needed to keep the wire hot. The temperature sensor measures ambient air temperature to adjust for differences in climate and humidity and helps regulate the temperature of the wire.

Symptoms of a bad mass air flow sensor include decreased fuel economy, starting trouble, stalling shortly after starting, rough idling, and jerking during acceleration. If your check engine light is on and your car has any of these symptoms, you can check the MAF sensor with an OBD-II code reader. Code P0101 means that the signal from the sensor is out of the expected range, meaning it’s likely time for a new sensor. If you don’t have a code reader, come down to your local AutoZone, and we’ll give it a look with our Fix Finder scan tool. Before getting a new sensor, try cleaning your MAF to make sure that the problem isn't simply due to a dirty sensor.
