The common problem is the little wire's in there have collected dirt. Remove the air filter and clean it good with some electric cleaner airasol. Dont use any thing else but a good electric contact cleaner.

Typically when the MAF is bad it will cause the vechile to stall constantly.

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

SOURCE: 98 chevy suburban, code reads mass air flow sensor

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.

Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

    What is a maf sensor


    A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine.
    The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder. (See stoichiometry and ideal gas law.)
    There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flowrate of intake air.
    Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0.0-5.0 volt or a pulse-width modulation (PWM) signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings for most post OBDII vehicles. Vehicles prior to 1996 could have MAF without an IAT. An example is 1994 Infiniti Q45.
    When a MAF sensor is used in conjunction with an oxygen sensor, the engine's air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop controller predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass.

    2003 Hummer H2 - Check Engine Light- P0171 and also been leaking/losing coolant a lot lately! Could the two issues be related or separate problems?


    Fuel system too lean (too much air, not enough fuel) vacuum leaks being the most common, you might want to check for a bad airflow sensor, plugged fuel filter, clogged fuel injectors, low fuel pressure, exhaust leaks, a bad PCV valve, bad oxygen sensor, stuck open purge valve. mass air flow (MAF) sensor are fairly common too. Sometimes the mass air flow sensor just gets dirty and gives false air flow readings.

    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.

        2003expedtioncodep2198 stuck rich


        The most common problem for this code is the mass air flow sensor. I would start with cleaning or replacing the mass air flow sensor. It is the sensor in the air tube for the air filter housing. Also make sure your air filter is not clogged. If you are going to clean the mass air flow sensor, make sure you use a suitable spray cleaner for electrical parts that is fast drying. DO NOT use compressed air to dry the sensor. There are very small wires and resistors inside of it that are very fragile and break very easily.
        Hope this helps. Good luck!

        It could be your MAF (Mass Air Flow) sensor. Do you have any SEL {Service Engine) light coming on?

The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine.
