What are the mass air flow sensor problems?
The mass airflow (MAF) sensor measures the mass (or weight) of the air as it passes through the throttle body to the intake manifold. It transmits this information to the engine control computer, which helps control the fuel-to-air ratio. Problems mass air flow sensors are very common. The MAF sensor could get contaminated or damaged.
What causes a MAF sensor to go bad?
The MAF sensor could get contaminated or damaged. Often this happens when an old or improperly installed air filter allows some unfiltered air into the engine or when oil from an oil-soaked air filter contaminates the air flow sensor.
What are the symptoms of a bad air flow sensor?
The most common symptoms from a bad mass air flow sensor are slow accelerating and reduced engine power. You can also notice a difference in the fuel economy as the main function of the mass air flow sensor is to let the engine know how much fuel it should inject.
How much does it cost to replace a MAF sensor?
MAF Sensor Replacement Cost. A Mass Air Flow Sensor is not so cheap but it is not very expensive either. You could get one for $120 – $300 to which you should add labor costs of $80 – $100. Therefore, on average you are expected to pay $200 to $400 in total for a mass air flow sensor replacement.
What happens when a mass air flow sensor goes bad?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.

What can cause a MAF sensor to fail?
The sensor element could get contaminated or damaged. Sometimes, an improperly-installed or ripped air filter can cause the MAF sensor to fail sooner. Over-soaking a washable air filter with oil can also cause troubles with the air flow sensor.
How often should I clean my mass flow sensor?
In most cases, a faulty mass flow sensor has a specific code that will generate during computer diagnostics, and is usually easy to determine with computer testing equipment. Generally, you’ll want to clean your mass airflow sensor either every six months, or every time you change your oil.
