How To Know That Your Vehicle's Mass Airflow Sensor Has Failed?

Trying to deal with a malfunctioning or damaged mass air flow sensor in your vehicle can be quite challenging and annoying at the same time. In case you're unaware of what the mass airflow sensor is, then you must know that it's located near the engine air filter and acts as a significant component of the fuel injection system. 

The mass airflow sensor has been solely designed to assess the overall amount of air that’s flowing into the engine, so that the correct ratio of fuel to air can be maintained inside the engine, ultimately allowing the vehicle to function properly. In this extensive guide, we’ll be sharing the various symptoms of a mass airflow sensor, so that you can take precautions and repair the same before the situation gets worse.

The Symptoms Of A Mass Airflow Sensor Failure

  1. Lighting Up Of The ‘Check Engine Light

According to a reliable company offering transmission repairs in Auckland, the ‘check engine’ light is the first sign of any component failure inside the engine. You can find the light popping up on your vehicle console, showcasing that there’s something wrong with the mass airflow sensor. 

The issue can be either that the mass airflow sensor has been damaged totally or not working as it is supposed to. Moments like these are when you should take your car to a professional mechanic and get it checked & fixed. 

  1. Vehicle Exhausting Black Smoke

If you notice black smoke is coming out of your vehicle exhaust, then it simply means that the mass airflow sensor inside the engine has been damaged and the overall amount of air inside the engine has reached maximum levels. 

When the mass airflow sensor gets damaged or starts to malfunction, it will not be able to get the air to fuel ratio correct, leading to an increase in the amount of mass air entry inside your car engine. When such a scenario takes place, you'll start noticing black smoke coming out of your vehicle exteriors. 

  1. Engine Is Misfiring

When the airflow intake inside the vehicle engine becomes imbalanced, it will make the engine misfire or function at a rough pace. Improper airflow inside the engine means that the combustion process will also turn out to be uneven as well, which leads to the happening of such a scenario. 

  1. Facing Difficulty In Starting The Engine

If you find it difficult to start your car engine, then most probably the fuel to air mixture inside the engine is not what it should be. Such a scenario will prevent the vehicle from starting until you decide to fix the mass airflow sensor.
