SOURCE: I have a 1999 oldsmobile

fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck

SOURCE: Where is the mass air flow sensor located on a jaguar x-type

hi from the uk the location of mass air flow sensor on x type jag is as follows==it is on the r/h/side of the air filter cover with jaguar embossed on top? this sensor is just prior to the intake hose that connects to the motorised throttle body from filter connections underneath it to unplug and meter is held by two screws ?if memory serves ? may i suggest you remove the large hose and use a little wd40 or similar to clean /lubricate the throttle butterfly in throttle body throat at this point so as to prevent future sticking upsetting of idling ? hope this helps ?

SOURCE: mass air flow sensor bad on 2002 monte carlo ss

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.

    P0100 - Mass Air Flow (MAF) Circuit Malfunction

    Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. Other MAF sensor circuit DTC trouble codes are P0101, P0102, P0103, and P0104.

    Symptoms:
    You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

    Causes: A code P0100 may mean that one or more of the following has happened:
    * The MAF may be disconnected, or a wiring connection may be bad
    * The MAF sensor may be faulty

    Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
    * Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
    * Unplug and reconnect the MAF wiring harness
    * Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
    * Replace the MAF sensor

    Then, like a reference guide check this TSB DTC P0102 MAF and this article about Mass Air Flow sensor, what does it do and how it does it.
    Test, check it and keep us updated.

    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.

      • Engine stalling
      • Lack of power

        Code 103


        P0103 - Mass Air Flow (MAF) Circuit High Input
        Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104.

        Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

        Causes: A code P0103 may mean that one or more of the following has happened:
        * The MAF may be disconnected, or a wiring connection may be bad
        * The MAF sensor may be damaged
        * The vehicle computer may be faulty (very rare)

        Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
        * Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
        * Inspect for any air leaks near the MAF sensor.
        * Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
        * Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
        * Replace the MAF sensor.

        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
        Rylee
