SOURCE: where is the mass air

98 jeep grand cherokee MAF
It located in the throttle-body. Look for electrical wires connected to it. It has an electrical resistor in the air flow stream that is kept cool based on the air flowing over it. The more air flow, the more electricity needed to maintain the resistors temperature. That's how it measures air flow.

SOURCE: Location of the Mass Air Flow Sensor?

Hi, the mass air flow sensor is on the intake tube just before the throttle body. these sensors are extremely sensative. there is a special cleaner that you can purchase at parts stores.

03 Nissan Altima showing codes P0304,P0102,P0154,P0113 what are they and how do i repair the problems.


Hi Chris.

p0304 = Number 4 Cylinder Misfire Detected

Faulty spark plug 4
Clogged or faulty fuel injector 4
Faulty ignition coil 4
Fuel injector 4 harness is open or shorted
Fuel injector 4 circuit poor electrical connection
Ignition coil 4 harness is open or shorted
Ignition coil 4 circuit poor electrical connection
Insufficient cylinder 4 compression
Incorrect fuel pressure
Intake air leak

The P0304 code means that the cylinder 4 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 4.


p0102 = Mass or Volume Air Flow Circuit Low Input

Faulty mass air flow sensor
Intake air leaks
Dirty mass air flow sensor
Dirty mass air filter
Mass air flow sensor harness is open or shorted
Mass air flow sensor circuit poor electrical connection

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner.
Reset code and drive vehicle.
If the code comes back, it may be necessary to replaced the mass air flow sensor.


p0154 = O2 Sensor Circuit No Activity Detected Sensor 1 Bank 2

Faulty Front Heated Oxygen Sensor Bank 2
Front Heated Oxygen Sensor Bank 2 harness is open or shorted
Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
Inappropriate fuel pressure
Faulty fuel injectors
Intake air leaks may be faulty
Exhaust gas leaks

Replacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem.


p0113 = Intake Air Temperature Sensor Circuit High

Faulty Intake Air Temperature (IAT) sensor
Dirty air filter
Intake Air Temperature (IAT) sensor harness is open or shorted
Intake Air Temperature (IAT) sensor circuit poor electrical connection

The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.



Hope this helps

    Where is air flow meter located


    The air mass sensor is located on the left hand side of the engine compartment. Follow the large hose which starts out as plastic down and to the front of the car. you will reach a rubber hose about 4" in diameter. It is attached to the back of the air mass sensor.
    They stopped using air flow meters in 1979 (I beleive) Then they switched to what they call a "hot wire air mass sensor".

    Where is bank 1 mass air flow sensor on 2000 cavalier


    There is only one Mass Air Flow sensor .No such thing as a bank 1 or bank 2 Mass Air flow sensor on a 2000 Chevy Cavalier. I think you mean Bank 1 O2 sensor . For that I need to know if you have a 4 cylinder or a V-6 . If it is a 4 cylinder it is located in the center of the exhaust manifold at the front of the engine under the hood. If you have a V-6 it is still loctaed in the exhaust maniifold but at the end of it where the exhaust pipes bolt up

    Where is the mass air flow sensor located on a 2003 Chevrolet S10 4-wheel drive


    The mass air flow(MAF) sensor is usually located between the airbox where the air filter is, and the throttle body.
    Look for the first big bundle of wires after the air filter and that's probably it.

    Where is mass air flow senser on a 1989 buick regal


    Hi

    Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
    On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

    Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

    Please do accept the solution if the issue is resolved or else revert for further assistance.

    Thanks

    How do I replace the mass airflow sensor on a 2004 Maxima?


    The mass air flow sensor will be in the air intake going to the throttle body. Look for a 3-4" hose, trace that back to a box looking component. The sensor should be in there.
