Mass air flow - S4wiki

Oct 11, 2020· A mass air flow (or MAF) sensor placed just before the intake manifold measures the instantaneous rate of air entering the combustion chamber. This is done using a thin wire or film suspended in the air stream. Hot wire MAF. A hot wire MAF is composed of a thermistor wire and an ammeter. Since the MAF wire is a "positive k" thermistor, the ...

IAT Resistor Mods vs Performance Modules vs Real Chips ...

Feb 01, 2010· Also, some Honda cars do not use air flow or air mass at all, but engine load by using a MAP sensor or “Manifold Absolute Pressure” sensor. The difference obviously is that while the AFM senses air flow, no matter the density of the air and the MAP senses engine load by vacuum or negative pressure, none of those two check the air density.

MAP Sensor (Manifold Absolute Pressure) Description

The Manifold Absolute Pressure sensor or MAP sensor is a sensor that is attached to the intake manifold on a car's engine. The MAP sensor responds to changes in the intake manifold pressure (vacuum) and provides a reading of "engine load". How it works is 5 volts DC is supplied to the sensor from the PCM (powertrain control module).
