How much does it cost to replace MAF sensor? The Average Mass Air Flow Sensor Replacement Cost Ranges from $240 to $330 Depending on if You Go to the Mechanic or DIY. Cost to DIY: $3 to $240, depending on whether you clean the MAF first or replace it. Urgency: Perform this service within a month to avoid vehicle damage.
How much does it cost to replace the mass air flow sensor? The average cost to have the mass airflow sensor replaced is between $200 and $350.
Is a MAF sensor expensive? Many mass air flow sensors will cost around $100–$150, however some will reach upwards of $400 — especially in higher end German makes. Most of these sensors sit on the air induction system, so installation will not be very expensive, usually around $20–$50.
What will a bad mass air flow sensor cause? A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.

How much does it cost to replace MAF sensor? – Related Questions
Can you drive with a bad MAF sensor?
Yes! It is possible to drive with the signs of a bad MAF sensor but for a specific duration. However, it will be recommended not to drive with a bad MAF sensor to lead the driver towards engine issues. Usually, people neglect what the MAF sensor tells them that often leads them towards the worst engine conditions.
How long does it take to fix a MAF sensor?
But this is a project we feel like most could take on themselves, armed with a just a screwdriver many of you will be able to replace your mass air flow sensors in under a half hour. If you’re not up to the job, give your mechanic a call and ask them how much it will cost to replace it.
Will a bad MAF throw a code?
Mass Air Flow Sensor Symptoms
Often, when there’s an issue with the MAF sensor, your car’s primary computer—often referred to as the powertrain control module (PCM)—will turn on the check engine light and store a diagnostic trouble code (DTC) in its memory.
How do you test a mass air flow sensor?
In modern cars, the only way to test the mass air flow sensor is with a scan tool. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. They compare the readings to the specifications or to the readings of a known-good mass airflow sensor.
What is the code for a bad mass air flow sensor?
P0101 is the general code for a problem with the Mass Airflow Sensor (MAS) operating range and/or an engine performance issue.
Can a faulty MAF sensor cause a misfire?
If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine’s computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire. Replacing a vacuum line that’s gone bad can potentially resolve the misfire.
Can a dirty MAF sensor cause a check engine light to come on?
Check Engine Light appearing on the dashboard
A bad mass air flow sensor will usually trigger a check engine light. This is because the ECU will detect an out of range value coming from the MAF sensor and the check engine light is its way of letting you know that something is wrong.
Can you clean a MAF sensor?
We recommend that you clean the MAF sensor every time you change your air filter. Spray 10 to 15 spurts of the mass air flower cleaner onto the wire or plate. Don’t scrub the parts; you may break the wire or damage the plate. Allow the MAF sensor to dry completely before reinstalling it in the air duct.
Can a mass air flow sensor mess up your transmission?
The Mass Airflow Sensor measures airflow into the engine intake assembly and is used to determine engine load. If it fails it can cause automatic transmission problems such as late harsh shifts, early soft shifts, or can result in no shifting at all.
Can a bad mass air flow sensor cause rough idle?
Mass Air Flow Sensor (MAF)
A dirty or faulty MAF will cause an engine to idle roughly, as well as stall when idling.
How often does a mass air flow sensor need to be replaced?
The life of your MAF sensor can be extended with regular maintenance and air filter replacement. A good rule of thumb is to drive every 10,000 to 12,000 miles. Mass airflow sensors (MAF) have no expiration date.
Why are MAF sensors so expensive?
A lower-tier automotive parts manufacturer is always squeezed hard for margins so that MAF sensor must cost $25+ to manufacture in high volume and parts may be the bulk of the cost, except for calibration.
Will my car run if I unplug the MAF sensor?
If you unplug the mass air flow sensor the car will start. If you try to plug it in while it’s running the car will die.
Is there a fuse for the MAF sensor?
There is a fuse for the maf sensor, but it is not the same one that runs most of the other stuff on that side of the engine bay. The code you get is for a dead maf, usually when the fuse pops.
Can a dirty air filter cause a P0101 code?
In vehicles with an oil-soaked aftermarket air filter, oil from the air filter can contaminate the MAF sensor element, causing the code P0101 or other MAF-related codes. In some Volvo cars, the code P0101 could be caused by a dirty throttle body or vacuum leaks in the PCV system (e.g. vacuum line to the oil separator).
What does Engine code P0101 mean?
Code P0101 Meaning
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range.
Can a dirty air filter cause MAF code?
The air filter may be the MAF sensor’s first line of defense via the engine’s air intake system, but a clogged, low quality or dirty air filter can actually become the source of MAF sensor damage if any contamination bypasses it.
How do I reset my mass airflow sensor?
Check if the engine light is still on after the Mass Air Flow Sensor was replaced. The entire system can be reset by unhooking the battery and leaving it unhooked for 10 minutes. Keeping the battery unhooked for longer than 10 minutes won’t hurt anything.
Can you have a misfire with no check engine light?
Often called “phantom” misfires. It’s possible to find a misfire in your Ford, even if there is no check engine light. All you need is an OBDII scanner with Mode 6 function. It is a common situation.
Can I use wd40 to clean MAF sensor?
DO NOT USE WD-40. Use a cleaner that is meant for electrical parts. Brake cleaner is essentially the same stuff. I’ve also used something called ‘thottle body cleaner’ whose label indicated it was safe for cleaning MAF’s.
Is Rough idle Bad?
This is not a normal operating condition. There can be a variety of reasons why your vehicle is idling roughly. The downsides of a rough idle can be reduced fuel economy, poor performance, starting issues, or potential major engine problems in the near future.
