Unplug the mass air flow sensor electrical connector. A mass air flow sensor MAF is used to measure the air flow that enters the engine at any given RPM range and is monitored by the vehicles computer to make adjustments to the fuel delivery and ignition timing.
How to Clean Nissan MAF Sensor.
How to clean mass air flow sensor. Place the sensor on a towel for cleaning. Apply the cleaner 10-15 blasts around the inside of the sensor will do. Also clean the sides of the part its housing its connectors and its terminals.
If you have a hot wire mass air flow sensor make sure the cleaner doesnt get onto the hot wires or plate. With the mass air flow cleaner and tools in hand locate the MAF sensor in the air duct between the air filter box and the throttle body. Before you remove the sensor use a camera to record the sensor setup and connections for reference later.
Carefully remove the sensor from the air duct and disconnect the electrical connector. Technically the MAF sensor measures air density and not the actual rate of flow. Air density is affected by temperature forced induction turbo and superchargers and altitude.
It is important that your MAF sensor is working properly to ensure the best fuel efficiency and engine function. There are a few types of mass air flow sensors. A mass air flow sensor MAF is used to measure the air flow that enters the engine at any given RPM range and is monitored by the vehicles computer to make adjustments to the fuel delivery and ignition timing.
When the MAF is in operation intake air from the engine passes through it which has impurities which are not removed by the air filter such as heavy air practicals. The problem that a dirty Mass Air Flow or MAF sensor can cause is not a major one but it can be quite an inconvenience and cause you to have to spend more time and money than you planned on simple car maintenance. A mass airflow sensor MAS determines the mass of air entering a vehicles fuel injection engine and passes that data to the Engine Control Unit or ECU.
The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine. When a vehicles mass airflow sensor is faulty or defective it can cause a variety of problems and usually results. Air Filter is missing.
Air Filter is torn or missing pieces. Air Filter is not properly set in place in its assembly. Air Filter Box assembly is broken letting in unfiltered air.
If any of the above apply to your car or truck your MAF sensors hot-wires are probably dirty and in need of cleaning. Here we walk through the simple steps involved with using mass airflow sensor cleaner httpamznto2AIxmie. In this particular case I was troubleshootin.
How To Power Clean Mass Air Flow Sensors - Fast EasyDisclaimer. Under no circumstances will proclaimliberty2000 be responsible or liable in any way for an. Mass air flow sensor cleaning.
How to clean mass air flow sensor in your car DIY with Scotty Kilmer. How to stop car hesitation by cleaning the MAF sensor. The Guideline of How to Clean Mass Air Flow Sensor with Alcohol Locate the Sensor.
First and foremost we cannot answer the question of how to clean mass air flow sensor with alcohol without being able to find where the sensor is. So after having all the supplies and tools together locating the mass air flow sensor is the next crucial step. You will know your MAF mass air flow is dirty from either noticing a decrease in gas mileage power or just an overall less smooth ride in your car.
You may notice an occasional hiccup where it feels like the car missed a beat. You will also usually be able to see dirt or grime on the MAF just from opening your hood and looking at it. The mass air flow MAF sensor part of your vehicles electronic fuel injection system is responsible for calculating the total amount of air entering the engine.
A faulty MAF sensor can cause your vehicle to run too rich or run too lean. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. The mass air flow sensor is a vital component of the vehicle.
It provides the air flow rate of air entering the combustion unit to the engine control unit ECU. Hence the ECU knows how much fuel mass should be delivered to the engine. If the sensor becomes dirty or clogged it can not measure the correct value of the air mass.
How to Clean Nissan MAF Sensor. Cleaning the MAF sensor on a Nissan is easy and takes less than 10 minutes. Pull the hood release and open the hood.
Locate the MAF sensor next to the engine air filter housing. Unplug the mass air flow sensor electrical connector. Remove the two screws that hold the MAF sensor secure and remove the MAF sensor.
