The prices vary based on where you go for servicing and what kind of car you have. The labor should cost you around $60, while parts are about $240. To get your mass air flow sensor replaced, you will pay about $300, on average. That information can be relayed as trouble codes or can activate an indicator light on the dashboard if a problem is detected. Sample Mass Air Flow Sensor Replacement CostsĪir is always passing through your engine, and the mass air flow sensor tells the car’s computer how much air is moving through there.

Mass Air Flow Sensor Replacement Cost Comparison.When replacing the mass air flow sensor, make sure the air filter is installed properly. If a sensor is dirty, your mechanic may suggest cleaning it (cleaning the airflow sensor is a delicate procedure) as a temporary solution sometimes it could help. If the air flow sensor is bad, it needs to be replaced. The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced. Sometimes the debris can fall in during the air filter replacement. Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and cause problems. For this reason, the air flow sensor connector terminals as well as the wiring needs to be carefully inspected. The air flow sensor connector could also cause the air flow readings to be out of range. Sometimes a poor electrical connection at

To use any phone app that connects to your car, you will need a Bluetooth adaptor that plugs into the OBD connector.

Is there a way to check the mass air flow sensor readings at home? Of course, for example, here we used the free Torque app to measure the mass air flow sensor readings at different RPMs (in the photo). Read more: Vacuum leaks: common sources, symptoms, repairs. That's why mechanics use a known-good sensor to compare the readings. Vacuum leaks affect air flow sensor readings too. A clogged up air filter or plugged catalytic converter can also cause lower air flow sensor readings. Low mass air flow readings do not mean the sensor is bad. The air flow depends on the engine volume, so a V6 or V8 engine will have higher readings. Of course, different engines will have different readings. In some rare cases a bad sensor may show higher readings. A contaminated or bad air flow sensor will, in most cases, show lower air flow readings than a known good one. Often mass air flow sensor readings are measured at idle, 1,000 RPM, 2,000 RPM and 3,000 RPM. Mass Airflow Sensor (MAF) readings of a 2.4L 4-cylinder engine at different RPMs. They compare the readings to the specifications or to the readings of a known-good mass airflow sensor. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. In modern cars, the only way to test the mass air flow sensor is with a scan tool. Trouble codes P0171 System Too Lean (Bank 1) and P0174 System Too Lean (Bank 2) are also often caused by a bad or contaminated mass air flow sensor. P0104 - "Mass Air Flow Circuit Intermittent" P0101 - Mass Air Flow Circuit Range/Performance P0100 - Mass Air Flow Circuit Malfunction The following trouble codes are usually associated with a mass air flow sensor:

#Mass airflow sensor cost code

This trouble code can be retrieved with a scan tool. When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.Ī problem with the air flow sensor could also alter the shifting pattern of the automatic transmission. As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.
