How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

How will a mechanic replace my mass airflow sensor?

A mass airflow sensor replacement requires the right tools and knowledge of a vehicle’s exhaust system. If your car has a bad mass airflow sensor, your mechanic will run a diagnostic test and replace it with these steps:
  1. Disconnect the electrical connector: Your mechanic will begin by disconnecting the electrical connector from the MAF sensor. 
  2. Remove the mass airflow sensor: Your mechanic will remove any clamps or screws holding the MAF sensor in place and then remove the sensor.
  3. Install the new mass airflow sensor: Your mechanic will attach the new MAF sensor and secure it with bolts/clamps.
  4. Reconnect the electrical connector: Your mechanic will then reconnect the electrical connector to the MAF sensor. 
After the replacement is complete, the mechanic will clear any codes and take the vehicle for a test drive to ensure everything is functioning correctly.

What happens if I don’t replace my mass airflow sensor?

A failing mass airflow sensor can lead to the following issues:
  • Poor fuel economy
  • Emission problems
  • Reduced engine performance
  • Rough idling
  • Engine failure
You should take your vehicle to a mechanic as soon as possible if you notice any signs of a bad mass airflow sensor to avoid steep repair costs down the road.

What is a mass airflow sensor?

The mass airflow (MAF) sensor monitors the amount of air passing into the engine and sends the information to the powertrain control module (PCM). The vehicle’s computer uses the information, along with information from the manifold temperature and
manifold absolute pressure (MAP)
sensors, to run the vehicle’s engine efficiently with an adequate fuel mixture with the right air-to-fuel ratio in the combustion chamber.
The MAF sensor is typically located between the air filter and the intake manifold of the engine.

When should I replace the mass airflow sensor on my car?

You should replace your mass airflow sensor if you notice the following warning signs:
  • Illuminated check engine light
  • Poor engine performance
  • Pause before acceleration
  • Trouble starting the vehicle
  • Engine misfires
  • Stalling
  • Black smoke from the exhaust pipe
  • Excessive fuel consumption
  • Poor fuel economy
Also, keep an eye out for OBD-II trouble codes P0171, P0174, or
P0102
, which all point to possible issues with the MAF sensor.

How often should a mass airflow sensor be replaced?

Mass airflow sensors do not have prescribed replacement intervals since they are meant to last the lifetime of your vehicle.
Routinely monitor your MAF sensor for signs of deterioration and take your vehicle to a mechanic if you believe a replacement is necessary.

Can I replace my mass airflow sensor myself?

An MAF sensor replacement should be handled by a certified mechanic with repair knowledge and expertise. 
Avoid changing your own mass airflow sensor if you have limited experience with DIY car repair

FAQs

Mass air flow sensors are made to last the lifetime of your vehicle, but they are prone to carbon buildup and usually need to be replaced over time. If your vehicle is over ten years old or you have more than 100,000 miles on your odometer, you should routinely inspect your mass air flow sensor and replace it if necessary.
While you can technically drive with a faulty mass airflow sensor, you shouldn’t. A bad MAF sensor can lead to poor fuel economy, and you’ll likely notice that your engine runs poorly. Your engine could also be damaged, which will leave you with a large repair bill. It’s best to take your vehicle to a mechanic immediately to replace your mass airflow sensor.
Common symptoms of a bad mass airflow sensor include:
  • Illuminated check engine light
  • Poor engine performance
  • Pause before acceleration
  • Trouble starting the vehicle
  • Engine misfires
  • Stalling
  • Black smoke from the exhaust pipe
  • Excessive fuel consumption
  • Poor fuel economy
Also, keep an eye out for OBD-II trouble codes P0171, P0174, or P0102.
A failing mass airflow sensor can lead to the following issues:
  • Poor gas mileage
  • Emission problems
  • Reduced engine performance
  • Rough idling
  • Engine misfires
  • Engine failure
You should take your vehicle to a mechanic as soon as possible if you notice any signs of a mass airflow sensor problem to avoid steep repair costs down the road.
