2.Mass Air flow Sensor (MAF
When you press the gas, the throttle opens allowing more air to flow over the hot wire. The passing air cools the wire down. The more air flows over the wire, the more electrical current is needed to keep it hot. The electric current is proportional to the amount of air flow. A smal...
3.Mass Airflow MAF Sensors
MASS AIRFLOW SENSOR OUTPUT MAF sensor output to the computer depends on the type of sensor used. The hot wire version, which Bosch introduced back in "79 on its LH-Jetronic fuel injection systems and is used on a number of multiport systems including GM"s 5.0L and 5.7L Tuned Port Injec...

5.Mass Air Flow (MAF) Senso
In some engines, a failed mass air flow sensor can cause the engine to crank but not start. Make sure to install MAF sensors properly, as improper installation can cause them to go out sooner. The hot wires inside these sensors are notorious for accumulating debris, air filter fibers, dust...
6.How to Test a Car’s Mass
Hot wire MAF sensors are the most common MAF sensor design. This type of sensor functions by heating a platinum wire or plate and measuring the current necessary to maintain that temperature as air flows over it. In contrast, vane MAF sensors rely on the position of a mechanical vane, which...
7.MAFTop Mass Air Flow Sens
Hot Wire MAF sensors – use a heated wire to detect airflow changes. As more air passes through, the wire cools down, and the sensor adjusts voltage output. Vane or K ármá n Vortex MAF sensors – older style, using a flap or vortex pattern to measure airflow. ...
