Repair and replacement of air flow meterĪ contaminated part can cleaned and washed, but if such proceduress do not bring sensor back to life, you will have to replace it.Įvery driver can handle the replacement. Voltage of a broken sensor will exceed the value of 1,4 V. Turn on engine without starting powerplant. Connect gage probes to flow meter signal cables “+” and grounds “-“. There is one other way, for which you will need a multimeter. If engine power has increased, then you should replace the regular sensor or clean it. It will also help if you connect a known good part. Also one of the most common sensor malfunctions is loss or wrinkling of rubber gasket at inlet opening. Have a visual inspection of inner part surface: it must be clean and dry. If you feel that engine started to work better, then the flow meter cannot be used anymore. Turn the sensor off and try driving without it. It is necessary to have additional diagnostics for spotting the failure.

Listed malfunction signs can stand not only for breakage of this particular part.

hose, which connects sensor with throttle module, is cracked.

oil is leaking into sensor through the crankcase ventilation.

dirt gets inside the part together with air flow.

problem with acceleration dynamics occurred.

Do not use brushes and cotton swabs to clear the dirt. Spray directly on the dirt to clear the build-up. If the rubbing alcohol or special MAF cleaner doesn’t remove all the dirt, try compressed air. Do not use gasoline or cleaning sprays meant for the brakes or carburetor. This can damage the sensor’s electronic components. Certain solvents leave a residue on the delicate air flow sensor wires. If not handled carefully, your MAF sensor can easily get damaged. Allow the sensor adequate time to dry completely before you reinstall. It measures the amount of air entering the engine, as well as the.

Be sure to spray the crevices and other restricted areas. The mass air flow sensor is a key part of your vehicles electronic fuel injection system. This helps to prevent damage to the delicate wires. It is best to hold the spray 2 feet away from the sensor when you spray. Lay a clean towel on a work surface and place the sensor on the towel. Obtain a special MAF cleaner or electrical component cleaner from an auto parts or electronics store. Be sure it dries completely otherwise the fluid can damage your engine. Allow 1 hour or longer for the sensor to air dry before you reinstall. Remove from the bag and place on a towel in a dry area. It works effectively with an oxygen sensor for improved accuracy. The information helps the engine control unit to determine the fuel level supplied to the engine. Its primary role is to detect the air mass flow rate getting into the engine. Leave the sensor in the bag for about 30 minutes to facilitate effective removal of dirt and grime. The mass airflow sensor is a critical part of the internal combustion engine. Shake the bag thoroughly to allow the alcohol to reach all parts of the sensor. Find out how DENSO MAF sensors can boost a vehicles reliability.

Fill a zip lock bag with 70/30 isopropyl alcohol. Mass air flow sensors ensure the engine has the correct air volume flowing through it. This is a simple yet effective solution that will get your air flow sensor clean. Up to two MAF Sensors may be used with your. This will help you to reassemble faster and in the right order. The Mass Air Flow (MAF) Sensor provides an input that directly measures the amount of air entering the engine. However, it helps if you mark the various attachment areas on the sensor as you remove. The sensor model varies from vehicle to vehicle.
