3 Simple Steps to Clean a Car’s MAF Sensor

If the MAF sensor is dirty you can clean it instead of replacing the expensive mass air flow sensor. As you should know by now, if you have a car, a MAF sensor monitors the temperature and weight of the air going into the engine. The on-board computer needs that information to calculate the correct amount of fuel for all engine operating conditions. Continue reading and learn how to clean car maf sensor.

The sensor works by heating a delicate platinum wire or plate and measuring the current needed to keep it at a constant temperature as air blows past it. Over time, dust and oil particles stick to the hot wire/plate and bake. Eventually, those particles isolate the wire/plate from the air stream. This causes starting, idling, and acceleration problems, as well as poor fuel economy.

The steps you must follow to clean a MAF sensor properly are as follows:

  1. Before you go to the shop, you need to remove the air duct between the air cleaner box and the throttle body to see how the MAF sensor is anchored. If you see Torx screws, buy a Torx tool and a can of mass air flow sensor cleaner or just an electronic contact cleaner. Do not use any other type of cleaner; since you could screw up the MAF yourself.
  1. With the mass air flow filter and the proper tools at hand, place the MAF sensor in the air duct between the air filter box and the throttle body. Before removing the sensor, please use a camera or your phone’s camera to record the sensor’s settings and connections for correct replacement later without making a mistake. Carefully remove the sensor from the air duct and disconnect the electrical connector.
  1. Spray 10 to 15 squirts of MAF sensor cleaner spray or electrical contact cleaner onto the wire or plate. Don’t scrub the parts presuming that they would be cleaner that way; as you can break the wire or damage the board.

Finally let the MAF sensor dry completely before re-installing it in the air duct.. Simple are these steps to clean a MAF sensor properly right? Remember to follow these steps to the letter and avoid completely damaging the sensor.
