2 julio, 2021

A vehicle’s mass air flow (MAF) sensor is designed to measure the amount of air flowing into the engine’s intake manifold. This information is then sent to the vehicle’s engine management computer, which injects the appropriate amount of gasoline into the cylinders. During daily driving, these sensitive MAF sensors are covered in dirt and oil. It is important to keep the MAF sensor clean for it to function properly. While there are alcohol-based cleaners available, you can save some money by cleaning the MAF sensor with isopropyl alcohol at home.

Step 1: you can clean the maf sensor with alcohol

Locate the mass air flow sensor on your vehicle, which will be under the hood. Most automobile MAFs can be found behind the air filter in the air intake.

Step 2: clean maf sensor with alcohol

Remove the MAF sensor from the vehicle. See your car’s service manual for instructions on how to remove the part. Removing the MAF sensor will facilitate work and cleaning.

Step 3: clean map sensor with alcohol

Pour rubbing alcohol into a clean spray bottle.

Step 4: how to clean maf sensor

Spray the alcohol generously over the MAF sensor. Make sure to cover the MAF sensor wires, the inlet, and all its cracks to thoroughly clean the part. Do not touch or rub the MAF sensor cables as they are very delicate and could break. The alcohol will remove all the impurities on its own.

Step 5: how to clean the maf sensor

Place the wet MAF sensor on a clean shop rag or paper towel. Put it in a place where it will not be damaged or dropped. Let the MAF sensor dry for at least an hour, until the part is completely dry. Replacing it before it is completely dry could give false readings and damage your engine. Put the MAF sensor back on the vehicle.
