I'm assumint that you are talking about Suzuki's "recall" for MAF sensor, and there isn't info.

The MAF sensor its on the Throttle Body next to the TPS. When the MAF sensor present problems the scanner send information about DTC P0171 Trouble Code - System Too Lean (Bank 1)

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time, and few symptoms are presents, as uou will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.

Causes: A code P0171 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak downstream of the MAF sensor.

Keep in mind this possible solutions, that include:
* In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect all vacuum and PCV hoses, replace if necessary
* Check for a dirty fuel filter and proper fuel pressure

Hope helps with this.

    2008 Chevy Kodiak c4500 duramax desiel code reader (Innova 3100 Can OBD2) shows P0102, what does it mean


    P0102 Chevrolet - Mass or Volume Air Flow Circuit Low Input

    Read more: http://engine-codes.com/p0102_chevrolet.html#ixzz38p5k1ZD8

    Possible causes - 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.

    I got the code from the OBD IT read a code of 23 and one of 36 now i need to find what it means


    code 23 is MAT too low.(mass air temp.) code 36 is Mass Air Flow Sensor Error

    The ECM receives a signal from the Mass Air Flow sensor depending on the amount of air entering the engine. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

        Does a 1996 Ford Taurus 3.0 have a hot wire type mass air flow sensor or a vane type? Would spraying carb cleaner into the MAF fix the problem of hard cold engine start? Once the engine warms up does the...


        TheMobilian, Yes, the Mass Air Flow is a Hot Wire type. There is a spray made for the mass called mas air flow cleaner. Regular cab cleaner is too harsh and can eat the coating inside mass air flow and it's delicate parts. Use throttle bore foam cleaner; it works like bathroom scrubbing bubbles and eats the gum and varnish. When engine warms up (closed Loop) both sensors work together giving input to ecm for output. Have someone with a live data reader read both sensors. (Let me know the readings?)


        Image Mass Air Flow(MAF)Sensor

        PURPOSE

        The Mas s Air flow (MAT) sensor measure s the amount of air flowing into the engine.

        This value is used by the Powertrain Control Module (PCM) in calculating the required

        Fuel injector pulse within order to provide the desired air fuel ratio. This input can also

        be used in determining Electronic Pressure Control (EPC). Shift and torque converter

        clutch scheduling.

        CONSTRUCTION

        The MAE sensor is located directly in the airflow path between the air cleaner housing

        and the throttle body. Ail air entering the intake manifold must pass through the sensor.

        Located in the MAT sensor directly in the airstream are two platinum wires, a hot wire

        heated by electrical current and a cold reference wire. The MAF sensor uses the air flow

        across these wires to calculate its output.

        OPERATION

        The hot wire is maintained at 200CC (392CF) above ambient temperature as measured by

        a constant cold *e. The current required to maintain the temperature of the hot wire is

        proportional to the air mass flow. The MAE sensor then measures the amount of

        electrical current required to maintain this temperature difference and converts this

        value to an analog DC voltage. This output varies directly with the mass air flow rate.



        Pay attention to the Paragraph about the torq converter.

        Need to clean massive air flow


        There is a special cleaner/solvent needed to clean mass air flow sensor. It can not leave a residual film. You can go to most any auto parts stores & locate it. It will say mass air flow sensor cleaner or safe to use on mass air flow sensors. I know a company called CRC makes the one I use. Just disassemble boots to both side of sensor & unplug wire connector. Clean off both sides of grid & allow to dry. Reassemble.

        Mass air flow sensor


        maf sensors identify the amount of air flow flowing in the intake. the sensor works with the throttle so it knows how much air is coming in to add the proper amount of fuel to mix with the air. Easy to pull and replace.
