Where is mass airflow sensor located

Most cars’ mass air flow sensors are located between the vehicle engine’s intake manifold and its air filter. The mass air flow sensor may also include an intake air temperature (IAT), the sensor in some cars.

Does MAF cleaner work

If you want to clean your mass airflow sensor, the best option is to opt for a MAF cleaner. It is one of the safest and most effective ways to clean the MAF sensor.

Your car engine performance relies so much on the MAF sensor. The car needs its readings to run smoothly and perform efficiently.

A dirty or dusty sensor will affect the functions of the engine, the fuel economy, and the gear. If you get a MAF cleaner, you can get rid of any dirt or stain that might be affecting the workings of the mass airflow sensor. You need to purchase a cleaner that is effective and has a maximum performance.

A MAF cleaner will benefit your car sensor in so many ways. Chemicals can harm the sensor and its housing but a cleaner will not do that.

MAF cleaners will improve its air and fuel ratio, improve horsepower, and reduce rough idling greatly.

If you want to start cleaning, you need to locate the sensor and detach it from the vehicle. If you have not done this before, you can check the manual of your car for instructions.

When you remove it, it will be quite easy to clean. Put isopropyl alcohol inside the spray bottle. Once it is inside the bottle, spray the alcohol all over the sensor.

Do not try to scrub the sensor wires to avoid breaking. The alcohol will get rid of all the dirt on its own.

Since the MAF is now wet, drop it on the rag or towel and let it dry for a few hours. Make sure you place it in a place where it will not get damaged.

Once it is completely dry, put it back in the vehicle. Placing it in the vehicle when it is wet will give false readings, and can destroy the car’s engine.
