What is the difference between an air flow meter and an air mass sensor?
Air flow meter is a generic term. There are 2 general types used in engines and several different designs. The most common type is a hot wire MAF (Mass Air Flow) sensor. It estimates the mass of air entering the engine by determining its ability to draw heat off electrically heated wire (s).
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 to test mass flow sensor without dismantling?
Mass air flow sensor testing with a multimeter without dismantling. Method applicable to all vehicles. Mass flow sensor, mass flow meter This video does not constitute or replace a real specialized technical manual, and was only made for convenience and educational purposes.
Which is the most common air flow sensor?
The most common type is a hot wire MAF (Mass Air Flow) sensor. It estimates the mass of air entering the engine by determining its ability to draw heat off electrically heated wire (s). The older version called a flapper MAF sensor, estimated airflow by how much it deflected a airfoil in the airstream.

How to avoid mass air flow sensor ( MAF ) misdiagnosis?
It is important to be mindful that the engine breather and vacuum hoses are in good condition and securely located before and after replacement of the MAF sensor. Leaks in any of these hoses can lead to misdiagnosis. When replacing a MAF sensor, it is good practice to replace the air filter at the same time.
What kind of MAF sensor do I Need?
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.
What does p0102 stand for in MAF sensor?
P0102: Mass Air Flow (MAF) Circuit Low Input. P0103: Mass Air Flow (MAF) Circuit High Input. MAF sensor malfunction that DOES NOT light up the check engine light (CEL).
