A mass airflow sensor measures the air going into your engine. It then sends this information to the engine control unit, which determines how much fuel the engine needs for combustion.<\/p>\n\n\n\n
When your mass airflow sensor acts up, your engine can\u2019t maintain the optimal air-to-fuel ratio. This can cause your engine to jerk, hesitate or stall. You might also experience a decrease in fuel economy.<\/p>\n\n\n\n
You won\u2019t want to drive for very long with a malfunctioning mass airflow sensor. The cost to replace one is typically between $240 and $684, including parts and labor.<\/p>\n\n\n\n
Prices for a mass airflow sensor vary quite a bit between manufacturers and have a large influence on the overall repair bill. Here are some sample prices for mass air flow sensors:<\/p>\n\n\n\n The make and model of your car partially determine how much you\u2019ll pay for a mass air flow sensor, but you can also often save money by buying an aftermarket part.<\/p>\n\n\n\n The next major piece of your final repair bill is the labor cost. It takes between about half an hour to an hour to replace a mass airflow sensor. Mechanics\u2019 per-hour rates across the United States range from about $110 to $175, meaning this job could cost $55 for half an hour of labor at the lowest rate and up to $175 for an hour at the most expensive rate. You might be billed for additional time to do diagnostics and testing.<\/p>\n\n\n\n If you want to save money on labor, it\u2019s easy to replace a mass airflow sensor on most vehicles. It\u2019s basically a straightforward swap of the old part with its replacement. In most vehicles, you can find your mass airflow sensor connected to your throttle body and air filter housing. Here are some general steps:<\/p>\n\n\n\n Your car will become increasingly unreliable and erratic the longer you delay the repair. Your car might be hard to start, perform poorly, and exhibit other engine-related problems.<\/p>\n\n\n\n If you\u2019re concerned about the cost of the repair, you can try cleaning your mass air flow sensor to see if this improves its performance. This involves similar steps as replacing it, but once you\u2019ve removed the sensor, you\u2019ll apply a cleaning spray to the interior and exterior, removing any corrosion, dirt, and grime. If your mass airflow sensor uses a hot wire, avoid getting any fluids onto its heating element. Once this is done, reinstall the sensor.<\/p>\n\n\n\nVehicle<\/strong><\/th> Part<\/strong><\/th> Source<\/strong><\/th> Cost<\/strong><\/th><\/tr><\/thead> 2017 Ford Escape<\/td> Mass air flow sensor CP9Z12B579B<\/td> Ford Parts<\/td> $175.09 MSRP<\/td><\/tr> 2019 BMW 530i<\/td> Mass Air Flow Sensor – Genuine BMW 13628605565<\/td> FCP Euro<\/td> $375.99<\/td><\/tr> 2019 BMW 530i<\/td> BMW Mass Air Flow Sensor – Bosch 13628605565<\/td> FCP Euro<\/td> $113.99<\/td><\/tr> 2018 Toyota Camry<\/td> Toyota Genuine Intake Air Flow Meter Sub-Assembly<\/td> Toyota Parts Center Online<\/td> $189.61 MSRP<\/td><\/tr> 2015 Honda Accord<\/td> Duralast New Mass Air Flow Sensor DL-3017<\/td> AutoZone<\/td> $58.99<\/td><\/tr> 2015 Honda Accord<\/td> Hitachi New Mass Air Flow Sensor MAF0122<\/td> AutoZone<\/td> $142.99<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n Labor<\/h3>\n\n\n\n
