Common problems with air mass meters.
As we already know, air mass meters are a beneficial in terms of economy and the environment. It saves your money, gives you extra fuel mileage etc, but like all gadgets and devices, air mass meters require maintenance and replacements. You should keep in mind that it is not a device that will last forever or at least a lengthy period.
Every time you drive your vehicle, air passes over the electrical wire or tube. Even though the air that has entered has been filtered by the panel filter inside the airbox, tiny particles like pollen and dust will still remain. In due course, these particles will build up and accumulate causing the efficiency of the air mass meters to drop down. Sooner or later, the air mass meter will stop working, generally resulting in poor performance and having a considerable impact on your vehicle’s fuel economy and power.
If your vehicle has trouble with acceleration like a hesitation or shows signs of poor idle, a bad air mass meter maybe the cause for it. The most reliable way to find out if your air mass meter has worn out is to check the vehicle’s computer diagnostic codes. If there is an occurrence of failure of the air mass meter repeatedly, this may be the result of you having an ‘aftermarket’ performance air filter that uses a filter element based on oil. Because of this, there is a chance that the mass airflow sensors are damaged.
Generally, air mass meter fail as a result of dust particles and water entering and clogging up the intake vane. The most frequent indications you will have from a bad air mass meter are an unpredictable or rough idle and poor performance. So it is very important that you make sure that the air mass meter and the air filter is cleaned or replaced regularly. But also remember, your vehicles lack of power and performance can be caused by other components or sensors.
Be careful when purchasing an air mass meter because there are cheap pattern parts that are in the market and these are usually manufactured in Asia. These duplicate parts can have problems concerning quality and performance. There are some other failings like an increase of fuel consumption, intolerable deviation and movement, bad engine quality, short life span and imprecise air mass measurements. Always buy original parts because buying cheap devices can cost you.
