The Mass Air Flow Sensor is probably the best way to measure
the amount of air an engine takes in (engine load). This sensor
not only measures the volume of air but also compensates for its
density as well. many imports are using engine
control systems based around this sensor.
There are two common designs of MAF sensors used in today’s
vehicles. One produces a variable voltage output (analog) and
the other produces a frequency output (digital). In either case
their operation is similar. Both outputs can be measured by a
scanner or a digital volt/ohm meter (dvom) that can measure
frequency.
Both designs work on the “hot wire” principle. Here’s how they
work. A constant voltage is applied to the heated film or heated
wire. This film or wire is positioned in the air stream or in an air
flow sampling channel and is heated by the electrical current that
the voltage produces. As air flows across it, it cools down. The
heated wire or film is a positive temperature coefficient (ptc) resistor.
This means that it’s resistance drops when it’s temperature drops.
The drop in resistance allows more current to flow through it in order
to maintain the programmed temperature. This current is changed
to a frequency or a voltage which is sent to the computer and
interpreted as air flow. Adjustments for air temperature and humidity
are taken into consideration since they also affect the temperature
of the heated wire or film.
Humidity always affects the density of air since humid air is less dense
than dry air. No other compensation is therefore needed for this factor.
Air temperature affects density since colder air is more dense than
warmer air. Many systems use an air temperature sensor to compensate
for this factor since similar amounts of air can enter an engine at
different temperatures. Some MAF sensors use an internal “cold” wire
to send ambient temperature information to the computer. Some use
an intake air temperature sensor in the manifold or the intake piping.
