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.

What happens when air flow meter goes bad?
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, causing additional damage to your engine.
What causes air flow meter failure?
Causes: You may have a faulty MAF meter, there could be an intake air leak, dirt on the airflow sensor or air filter, the MAF sensor harness is either opened or shortened.
What does the airflow meter do?
An air flow meter is used in some automobiles to measure the quantity of air going into the internal combustion engine. All modern electronically controlled diesel engines use an air flow meter, as it is the only possible means of determining the air intake for them.
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 you drive with a faulty mass air flow sensor?
Yes, you can drive within such a sensor situation, but you can ride a car or truck for a specific duration. ... The bad mass airflow sensor problems can cause different drivability issues. The drivers can easily experience the lack of power in the engine, no-engine start, poor acceleration, and more during the drive.
How much does it cost to replace a mass air flow 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 long does it take for mass air flow sensor to reset?
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.
Why does my car run better with MAF unplugged?
The MAF sensor measures air weight in grams per second and air temperature and if either of those two are off then the ECU may command a leaner or a richer mixture. By disconnecting the sensor the ECU switches to limp mode and the car may idle better .
Can a dirty air filter cause shifting problems?
Performance issues in your vehicle's engine can be caused by a dirty cold air intake. A decrease in gas mileage, hesitation when shifting gears, and a dirtier air filter are some of the common problems.
Can a bad MAF cause limp mode?
When the MAF sensor goes bad, the computer sets a trouble code and illuminates the Check Engine light. It then defaults to a generic fuel map which allows the engine to run, but doesn't work well because it's really a guess. This is sometimes called “limp-home mode”, it's only there to let you get off the road safely.
