4/11/2018· A brief background on what a MAF does. A Mass Air Flow sensor measures the volume of air entering an engine. By passing a current through a wire and measuring the change of resistance of the wire the ECU can measure how much air is entering the engine at a given time. Mass Air Flow Sensors are usually easy to locate and if they have done a lot of miles they could well benefit from …
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.
18/6/2021· Cleaning or replacing the mass air flow sensor sooner rather than later will avoid these potentially more serious and expensive problems.

I have just turn 17,000 miles and it seems surprising that the MAF would be bad with such low mileage. Keep in mind that I have only put 2K on it in the past year.
11/8/2017· Mass Airflow Sensor Replacement. Get a Quote. Jessica Howe. Automotive Mechanic. 5 years of experience. Hello, thank you for writing in. The mass air flow sensor should not be cleaned with carburetor cleaner. Carb cleaner leaves an oily type residue that is not good for the electronics within the MAF sensor.
22/10/2018· To clean the sensor surface, you should only use a Mass Air Flow Sensor cleaner (MAF cleaner) or electrical contact cleaner. Try not to touch the sensor surface with your hands as grease and dirt from your hands can damage it. Let the sensor surface dry completely before refitting it to the vehicle. 4. Refit the mass air flow sensor to the car.
8/6/2020· 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. As a result, a bad mass air flow sensor causes various driveability problems, including a nostart, stalling, lack of power and poor acceleration.
