CRC SensorKleen Mass Air Flow Sensor Cleaner dissolves dirt, grease and fluxWill not harm sensitive electronics or plasticsImproves the air to fuel ratio of your vehicleThe mass air flow sensor (MAF) is used to measure the amount and temperature of air that is entering the engine at any one time. The mass air flow sensor senses the total amount of air passing the sensor and allows the fuel injection system to adjust the fuel mixture to compensate for cold weather and/or high altitude conditions. The MAF also incorporates an internal intake air temperature sensor which measures the temperature of the intake air.The first indicator that you might have a problem with the MAF is the presence of a check engine light (CEL) on your dashboard. The check engine lamp can be caused by a wide variety of problems with the engine: you need to read the codes from the computer to get a starting clue as to what the problem is. However, the engine will not be operating at peak efficiency, and you will most likely experience a loss in power and a decrease in gas mileage as a result.

It's best to get the problem taken care of relatively quickly, as running the engine in this condition can potentially cause damage to other components like the catalytic converters.Vacuum leaks and other air leaks in the system can cause MAF sensor errors. If you have a crack or leak in your air intake downstream of the sensor, then the MAF will be sensing less air than the engine is actually receiving. You should carefully inspect all of your hoses, clamps and intake tubes for air leaks prior to replacing the sensor.You will need to remove the engine covers and air intake ducts to perform this work. Please see our article on replacing your air filters.The new MAF comes complete in the air body housing so you will have to remove the complete housing to replace it. This article also shows you how to remove the sensor from the housing to clean it. Make sure you only clean it with MAF sensor cleaner and that you never touch the sensor face with anything or you will destroy it. With the air filter covers off you can see the MAF sensor housing at the rear of the engine (red arrow) along with the harness (yellow arrow).

Disconnect the harness (red arrow) by squeezing the two clips together and pulling it from the housing. Use a flat head screw driver and release the clip (red arrow) that holds the sensor housing to the intake manifold (yellow arrows).mountain air cleaning riverton wy Slip the mount off the housing. lg air purifier iranHere you can see the center clip (red arrow) and the clips that hold it to the manifold (yellow arrows).vornado whole room air purifier Wiggle the housing off the end of the throttle body. You will have to disconnect the breather tube (red arrow) to remove it from the engine. This photo illustrates the two clips (red arrows) that hold the housing to the throttle body. There is a small clip (red arrow) on the rear of the housing that you need to slide back so you can pull the MAF sensor housing from the other housing.

There are two T20 Torx security screws (red arrows) that hold the MAF sensor in the housing. You can remove these with the housing in or out of the car. Only clean the sensor with MAF sensor cleaner and never touch the sensor film (red arrow) with anything. 1985-1988 Volvo 740 Mass Air Flow (MAF) Sensor Maintenance 1985-1988 Volvo 740 Preparing Car For Work Some of this guide's text is confusing, duplicated, or off-topic. Clarify it by editing! Always take the negative terminal off first. '''General Tip After disconnecting the battery leave the car for about 10 mins , This lets any residual energy left in the electrical system to dissapate. It is good practise whatever the job Unlatch the 2 clasps. Loosen screw on metal band. Press on the 2 latches, pulling the cable away from sensor. Disconnect hose from MAFS. Steps 4-6 are for cleaning only. Spray MAFS cleaner along direction of travel, shown by arrow. Clean electronic coupling with electronics cleaner.

Inject conducting lubricant into MAFS electronic coupling. Re attach MAFS to air filter housing and intake hose. Tighten screw on metal band. Latch clasps on either side of MAFS. Re attach electronic cable to MAFS. To reassemble your device, follow these instructions in reverse order.Motorcraft® Mass Air Flow (MAF) Sensors New and remanufactured available to help meet your customers’ needs Units come ready to “plug and play,” with no need for modifications Optimizes fuel consumption and emissions to help ensure vehicles meet various state smog-level requirements Tight tolerance ranges help minimize repeat repairs and false “Check Engine” warnings Design includes OE innovations and upgrades View Fuel and Emissions Video Search all Motorcraft® MAF sensors by VIN, vehicle application or part number IP address: 54.245.37.66Time: 2016-09-24T10:40:08ZURL: http://www.youtube.be/watch%3Fv%3DxzVNjrWdixMAuto Parts/Auto/Air Management Sensors/Mass Airflow Sensor/ See all Mass Airflow Sensors
