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.
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.
This sensor is almost always ntc in design (negative temperature
coefficient). That is, it’s resistance goes up as air temperature goes
down. This “thermistor” works just like a coolant temperature sensor
and usually has identical resistance to temperature values. By the way,
these values are very different from manufacturer to manufacturer
and are available in most repair manuals. They are also programmed
into scanner software.
Now, as we discussed, the MAF sensor sends either a variable
voltage or a changing frequency to the computer. The computer
is programmed to accept this information when the car is running
in any mode. For example, idle rpm will send a low voltage or low
frequency and a high revving engine will send a high voltage or
high frequency to the computer along a specific wire (the MAF
signal wire). If the signal is not present when it should be and
within a programmed parameter, say high voltage at high throttle
opening, the computer will set a code.
So, there are several things to consider whenever there is a code
which points to the MAF sensor as the problem:
1. Derive the code(s) by the manufacturer’s recommended method.
2. Look up the code(s) in a service manual.
3. Read the explanation(s) carefully!
4. A code that indicates an out of range signal is often an
indication that another sensor, like the throttle position sensor
or the rpm input signal is contradicting the MAF signal. The
cause might be the other sensor or signal being out of adjustment
or faulty.
5. A code that indicates a low MAF signal may be set by various
problems.
These include the following:
1. A bad MAF sensor (internal fault)
2. Any wire on the MAF sensor circuit including:
A. The 12 volt feed wire which connects the MAF to the
battery through the ignition switch or through a relay as
in many GM applications
B. The MAF ground wire
C. The output wire
D. The MAF or computer connectors
E. The computer
