What is a mass airflow sensor do?
What is a mass airflow sensor do?
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. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine.
What do you need to know about a mass air flow sensor?
Signs Of A Failing Mass Air Flow Sensor. Your Mass Air Flow Sensor (MAF Sensor) is a piece of technology within your engine which tells your car’s computer how much air is entering the engine. This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.
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.
What causes an air flow sensor to fail?
An improperly installed or collapsed air filter can cause the air flow sensor to fail sooner. Over-soaking a washable air filter can also cause problems with the air flow sensor. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel.
How does the mass airflow sensor work in an engine?
The mass airflow sensor, or mass airflow meter, measures the amount (mass) of air that is entering the engine and then conveys this information to the ECU, or engine control unit. This ready flow of information allows the ECU to mix the proper amount of fuel with the airflow in order to create efficient combustion.
Can you drive with a bad mass air flow sensor?
You can drive with a bad mass airflow sensor, but you shouldn’t as it can lead to the damage of other engine components and your vehicle will use a lot more fuel than it should, especially at higher speeds.
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 much does it cost to replace mass air flow sensor?
The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced. If the air flow sensor is bad, it needs to be replaced. It’s a fairly simple job. The part costs from $89 to $380.
