2011 NISSAN ALTIMA MASS AIR FLOW SENSOR PROBLEMS

When you step on the gas pedal to accelerate the vehicle, you may experience
hesitation as you are moving forward. Read also: 5 Symptoms of a Bad Air Filter
5) Acceleration Hesitation If the engine control unit cannot receive information
about the airflow, then it won’t know how much fuel to inject into the internal
combustion chamber. It may send accurate airflow information to the engine
control unit at first, but then it will stop doing so shortly after. This
symptom may occur if your mass air flow sensor is just starting to go bad. But
if the engine begins to stall shortly after, then it is obviously isn’t. When
you start up your vehicle, and the engine turns on, you may think everything is
fine. This will cause the engine to simply not have enough power output for the
current demands. This means that more gasoline and air will be required in the
internal combustion chamber.īut if you have a bad mass air flow sensor, then you
will likely not get enough gasoline to accommodate this load.

Whenever you increase the load of your vehicle, it will put more demand on the
engine to generate enough power to sustain this weight. If the engine is going
to successfully turn over, then you need to correct this problem so that the
spark plugs can ignite the proper mixture.

This is understandable with a bad mass air flow sensor because it will cause the
internal combustion chamber to have an inadequate mixture of air and gasoline.
When you put your key into the ignition and twist it, you may find the engine is
difficult to turn over or start altogether. This will ultimately hinder the
performance of the engine. Meanwhile, there is very little gasoline being burnt
in the process.

The “lean” word refers to the abundance of air and not enough fuel. When you
have a lean idling problem with your engine, this is the result of too much air
and not enough gasoline getting mixed together in the internal combustion
chamber. Sometimes these symptoms may be due to other reasons, but you should
still have your mass air flow sensor inspected if you experience at least a few
of these symptoms that are listed below.

You just need to be able to recognize the symptoms as they occur so that you
will know to associate them with a possibly faulty mass air flow sensor. A bad
MAF sensor is fairly easy to detect from the very beginning.
