How Much Does Mass Air Flow Sensor Repair Cost
Terminal Updated on November 2, 2022
As you probably know, the internal combustion engine of your vehicle needs the correct remainder of air and fuel in its cylinders for a successful combustion to have place.
Need immediate help for your car problem? Chat online with an good:
This will generate the proper amount of power needed to satisfy the demands beingness placed on it by the accelerator. This is all managed past the MAF (mass air flow) sensor and engine control unit.
How a Mass Air Menstruum Sensor Works
When air from the outside enters the engine, the mass air flow sensor detects the mass of this air. Once the air menstruation mass is calculated, the sensor sends this information to the engine control module.
From in that location, the unit tin correctly tell the fuel injectors how much fuel to inject into the engine cylinders. This balances the air and fuel ratio to promote successful combustion. You see how all these components work together like this?

Top 5 Bad MAF Sensor Symptoms
If your mass air flow sensor e'er goes bad or malfunctions for some reason, it will ship the wrong data near the airflow mass to the engine control unit. This will jeopardize the entire internal combustion process because the engine won't receive the proper amount of fuel from the injectors.
Remember, the engine control unit of measurement needs the correct mass air flow information to know how much fuel to put into the engine cylinders. If the information is incorrect, and then an wrong amount of fuel will exist put into the engine causing information technology to run either likewise lean or too rich.
To assist you catch this problem early on, here are five of the most mutual signs of a faulty mass air menstruum sensor that you can watch out for. Some of these symptoms can exist caused by other bug with the vehicle.
But if you find at least ii or three of these symptoms happening at the same fourth dimension, you lot can probably pinpoint the problem directly on MAF sensor that's non working correctly.

#1 – Rough Idling
When the mass air flow sensor is bad, the engine command unit will non receive any information from it. As a result, the engine command unit of measurement won't know the proper amount of fuel to have injected into the cylinders.
This will cause the engine to feel rough idling whenever y'all park or cease the vehicle. Watch the tachometer on your dashboard and see if your RPM speed fluctuates rapidly in an idle position. If information technology does, then you probably accept a bad mass air flow sensor to worry about.
#2 – Engine Stalling
You may start your vehicle, and everything will seem fine. Withal, shortly subsequently you begin driving the vehicle, the engine may stall at some unexpected moment. This will prompt you lot to take to beginning your engine over again.
If you lot keep experiencing this engine stalling problem, effort to become your vehicle to the nearest car mechanic before you cannot start your engine at all. If you already experienced crude idling before this symptom, and then stalling will further confirm that you have a bad mass air flow sensor.

#iii – Acceleration Hesitation
If you stride on the gas pedal to accelerate your vehicle and feel hesitation as y'all try to go faster, y'all might have a bad mass air flow sensor. This can definitely be confirmed if the hesitation is followed by jerkiness.
The automobile volition kickoff to jerk a lot as you try to go faster. These are all signs that your engine is non receiving the correct amount of air and fuel. Although other issues tin crusade this to happen, cheque the mass air flow sensor to see if that is still functional.
#4 – Engine Runs Too Rich or Also Lean
A rich fuel to air mixture in the combustion sleeping accommodation means there is more fuel than needed in relation to the air in the cylinders. If yous have a lean fuel to air mixture, then not enough fuel is bachelor for the amount of air in the cylinders for ideal combustion.
Either case can spell problem for the combustion process of the engine considering it volition either cause insufficient ability to be generated or also much fuel to be consumed.
The worst part is that sometimes you won't even notice this problem unless you go on track of your miles per gallon. If you notice that yous get fewer miles per gallon, so you lot probably have one of these two conditions.
#5 – Bad Fuel Economic system
If your engine runs as well rich because of a bad mass air flow sensor, you tin can expect poor fuel economy as a result. The engine control unit might transport likewise much fuel into the cylinders of the engine considering it doesn't know how much air flow mass is in there.
The more than fuel that is consumed per combustion, the more than information technology will drain your wallet at the gas pump.
MAF Sensor Replacement Cost
The replacement cost of a mass air flow sensor can anywhere from $lxxx to $380. The cost of the function lonely is about $thirty to $300 with the lower end of the range for common aftermarket mass air flow sensors while college quality or more than complicated OEM sensors are more expensive. Await to pay around $50 to $80 in labor if you lot let a professional person to supersede information technology.
This is non a hard chore to perform yourself since the MAF sensor is usually located in an easy to reach area on top of the engine. So if you lot have even the most basic mechanic experience, it shouldn't take you more than than a few minutes to supercede it.

If y'all're non confident in your abilities or want to make sure you're getting the correct part, go to a professional mechanic and have them do the job for you. The biggest expense will be for the price of the part anyway.
You won't be able to terminal also long without a fully functional mass air flow sensor. Your ability to properly control your vehicle will be compromised.
It is better to just replace the sensor as presently as possible earlier your problems become worse. More importantly, you should do so before your engine gets damaged beyond repair.
