Best Mass Air Flow Sensor for Good Fuel Efficiency

Mass Air Flow Sensor

With the ever toughening economy, efficient fuel consumption is on top of any driver's list. One way of ensuring the engine works as expected is by ensuring a faulty sensor is not sending wrong readings to the engine computer. Finding the best mass air flow sensor will increase the efficiency of your driving by a considerable margin. Of course, you need to replace a bad sensor as soon as you discover one to avoid using too much fuel. We will give you our top picks for the most efficient mass air flow sensors available in the market to improve your fuel efficiency and make your driving worth the while.

What is a Mass Airflow Sensor?

The most critical components of an electronic fuel injection system are mass airflow sensors. The MAF sensor is installed between the intake manifold of the engine and the air filter. The MAF sensors analyze the air flowing into the engine and send the analysis to the engine computer for efficient fuel consumption. The engine computer then calculates the amount of injected fuel into the engine. The analysis is then used to achieve a good fuel ratio by preventing too much air from getting into the engine when there is little fuel.

Modern cars have more advanced mass air flow sensor technology that regulates the air flow correctly and has an intake air temperature sensor. As air flows into the engine, the IAT sensor takes the temperature readings used by the computer to calculate the air density that informs the fuel delivery. Now that we have an idea of what the mass airflow sensor does, let us look at the best options to blend in with other car parts for the smooth functioning of your vehicle.

How to Care for the Mass Airflow Sensor

Dust is an enemy of the mass air flow sensor. Therefore, air filters play an essential role in the well-being of a MAF sensor. A dusty sensor may end up sending incorrect information and may need to be replaced prematurely. One way of protecting the sensor is to ensure the filter is always clean and free of dust as much as possible to maintain an efficient performance of the sensors. Dirt sticks on the hot wire leading to faulty readings of the air mass flowing past the sensor.

Apart from regularly cleaning the filter, it is vital to clean the sensor for efficient gas consumption. Dirt can find its way to the mass air flow sensor that needs to be as clean as possible to measure and send the correct heat and air flow readings. A sensor cleaner comes in handy when cleaning the sensor by restoring the idle air controller function. There are many mass air flow sensor cleaner brands out in the market that will help the sensor work properly to read the air temperature entering the engine.

Be cautious when removing the air sensor because it has the potential of breaking. The sensor is very fragile and costly. Open the airbox carefully and try not to touch any wires because they are small and very delicate. Once a wire breaks, you will have to replace the sensor wholly. Apart from using a MAF sensor cleaner, you can dip the sensor in a bag of rubbing oil to remove the debris that may have accumulated on the MAF sensor. Ensure the engine is off and not running before removing the mass air flow sensor to prevent short-circuiting of any kind.

After cleaning the mass airflow sensor, ensure it is dry before reinstalling it to the car. Let the sensor sit for about 20 minutes before taking it back into the car.

Symptoms of a Faulty Mass Air Flow Sensor

Detecting a faulty sensor might not be easy sometimes until it is too late and you have used more fuel than you should on a typical day. It is vital to be keen and catch any malfunctions in time to save you on costs and ensure your car's smooth running. Here are things to check for to ensure the mass air flow is functioning smoothly at all times.

a) Troubled Accelerating

The mass airflow sensor sends signals to the engine computer to control the fuel-to-air ratio for efficient fuel consumption. Once the sensor is faulty, the ratio will be messed up, and the results experienced when accelerating. The fuel injection is limited when the sensor is sending the wrong readings at the wrong time. The air density needs to be read accurately by the mass air flow and air intake temperature sensors.

The air flow meter measures the ambient air and its density. The system is electronically controlled after analyzing the readings sent by the mass air flow sensor to the engine computer. Ensure the sensor is clean to send accurate readings of the air mass for smooth acceleration.

b) Rough Idle

When you notice that the engine idle is not as smooth as possible, there is possible trouble with the mass air flow sensor. The sensor is responsible for ensuring the engine computer gets correct readings for appropriate fuel injection. A smooth flow of fuel results in the proper functioning of the engine when idling. Once the engine is not running smoothly, there is a high chance that your MAF sensor is dirty or faulty.

c) Check Engine Light

When the check engine light turns on to show a fault somewhere, like on the oxygen sensors, spark plugs, or the mass air flow sensor. Trace the airflow from where it gets in, and you might find that the mass air flow sensor needs to be replaced. The mass air flow sensor is the most sensitive part of the whole system that needs to be checked frequently. Coupled with other symptoms, it should be easier to zero in on the mass air flow sensor as the defective part in the system.

d) Black Exhaust Smoke

Black exhaust smoke is a definite sign that something is wrong with the engine. The engine should not be running lean or too rich at any given time. The air to fuel ratio getting into the exhaust should be accurate at all times in the air cylinder. The air getting into the intake manifold should be just enough to burn the available fuel in the cylinder. The black smoke may end up masking a hot wire type of sensor, causing a protector.

Air flows into the engine at a regulated rate determined by the computer that gets its signal from the mass air flow sensor. Once the wires of the mass air flow sensor are coated in dust, the temperature readings and the air density readings will be wrong, leading to a wrong response. A new mass air flow sensor will measure the vital readings leading to a more efficient engine function.

e) Hesitation or Sudden Jerking

Jerking or hesitation is a more severe symptom of a faulty mass air flow sensor. When the car suddenly jerks or hesitates when you are accelerating, the potential of getting an accident is increased. For example, say you were trying to overtake, and then suddenly your car acceleration hesitates, putting you in a rather dire situation. The problem can be traced back to the mass airflow sensor sending wrong readings. To stay safe at all times, ensure you check the mass air flow sensor once every while and pay attention to the symptoms that may point to a faulty sensor. Also, ensure the sensor meets or surpasses the OE specifications before making a change.

Final Take

The mass air flow sensor is the most vital part of your car that will determine how safe it is for your vehicle to hit the road. Fuel efficiency is a weighty matter in these times when fuel prices are skyrocketing globally. A suitable sensor gives a good diagnosis for the car system to respond appropriately when you are driving. The weather keeps changing and seasons too. A suitable sensor will keep your car on the road seamlessly through every season.
