Question about 1992 Buick Park Avenue

1 Answer

Where is the Mass Air Flow Sensor located.

Hi there, I have been told I have a bad mass air flow sensor, the car now won't idle, but had been running fine. Is this a fairly easy thing to install myself? I have found the part for $120, and intend to check the connectors first, and clean the old one with carb cleaner. Trouble is, I'm having a hard time finding it. Any tips?

    Faulty air flow meter


    If the idle air control valve is bad, you'll have trouble with rough idle, stalling, surging etc. along with the sluggishness. The Mass Air Flow sensor is more likely the cause. Not sure where you're located but at AutoZone, you can return the part if you have to.

    P0102 - Mass Air Flow Sensor Circuit Malfunction

    The mass air flownissan-maxima-maf-sensor.jpg or MAF sensor is placed in the intake air duct between the air filter and the engine intake manifold. The MAF sensor measures the amount of intake air flow. The MAF sensor converts the air flow measurement into a voltage or frequency signal, with the voltage or frequency changing proportionally to the amount of air flow. The air flow sensor signal is monitored by the engine computer (ECM). The engine computer (ECM) uses the mass air flow signal to know the engine load and to calculate the proper amount of fuel injected. If the signal from the mass air flow sensor is out of expected range, the ECM detects a fault and sets the code P0100. For example, the mass air flow sensor signal could be higher than expected when the engine is not running or lower than expected with the engine running. A car with the code P0100 may have some driveability issues, such as stalling, lack of power, surging, hesitation, etc. In some cars, the code P0100 can cause the fail-safe mode where the engine speed would be limited to 2,500 - 3,000 rpm.
    If there are other trouble codes present, they might need to be looked at first. Checking the freeze frame may help, as it may contain some important information. The freeze frame is a snapshot of the engine parameters at the moment when the fault was detected. The freeze-frame may show whether the vehicle was running or stopped, whether the air-fuel ratio was lean or rich, was the engine was cold or warmed up at the time of the malfunction. Read more about the freeze frame.


    Read more about mass air flow sensor.

    What could cause the code P0100:
    - faulty or contaminated mass air flow sensor
    - open or short in the mass air flow sensor electrical circuit
    - open or short in the sensor power or ground circuit

    - other electrical problem with the MAF sensor wiring, (corroded wires, bent terminals, bad ground connection, burned fuse, etc.
    - vacuum leaks
    - restricted air flow at or before the air filter
    - wrong air flow sensor installed
    - problem with ECM





    P0102 - Mass Air Flow Sensor Circuit Low

    The mass air flow or MAF sensor measures the amount of air entering the engine. The engine computer (ECM) uses the mass air flow signal to calculate the amount of fuel injected (read more how the MAF sensor works below). The code P0102 is set when the signal from the mass air flow sensor is lower than expected. Often a car may exhibit some driveability symptoms, such as lack of power, surging, hesitation on acceleration, hard starting, pinging (detonation), or rough idle when started cold. Often the codes P0171 or P0174 could also be stored along with the code P0102, as the incorrect air flow signal can cause the engine to run lean. The codes P0171 and P0174 indicate a lean condition. Checking the freeze frame might help in the diagnostic process. The freeze frame is stored in the ECM along with the trouble code. The freeze frame contains some recorded parameters (e.g. vehicle speed, engine temperature, fuel trim) at the moment when the fault was detected. The freeze frame can also be accessed with a scan tool.



    What could cause the code P0102
    - faulty or contaminated mass airflow sensor
    - debris blocking the air flow at the mass air flow sensor
    - unmetered air leaking past the MAF sensor (vacuum leaks)
    - PCV system vacuum leaks
    - restricted or collapsed intake air duct
    - dirty or restricted air filter
    - restricted air screen before the air filter
    - improper application of aftermarket components (e.g. cold intake, modified air filter, etc.)
    - wrong air flow sensor installed
    - electrical problem with the MAF sensor wiring, connector, power supply or ground.
    - problem with ECM
    - in some cases other issues with the fuel injection system like a clogged catalytic converter or a faulty manifold absolute pressure sensor (MAP) can also cause the code P0102.

    2003 Grand Am Has P0102


    It is not an ECM/PCM problem.
    P0102 - Mass or Volume Air Flow Circuit Low Input
    Possible causes- Faulty mass air flow sensor
    - Dirty mass air flow sensor
    - Dirty air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor electrical circuit poor connection
    - Intake air leaks Tech notes 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

    My chevy blazer 2000 ha a p0101 code changed the mass air flow sensor still does not want to accelerate


    Hi there:
    This code is set when the MAF (Mass Air Flow) meter is not sending the PCM the correct information. This can be due to a bad conection of the rubber intake hose between the MAF and the Throttle plate opening, a dirty air filter, a dirty mass air flow or a bad mass air flow.



    Most programmer have you tie into the iat sensor in the mass air flow. this can cause the the iat sensor oto short out.


    Hope helps.

    The car stalls out while driving sometimes,but it will start right back up with problem. Theres no engine light on, or anything else on.


    . Check the Mass Air Flow Sensor voltages. Verify good battery voltage to the Mass Air Flow Sensor on the White/Black wire. Verify good grounds for the Mass Air Flow Sensor on the two Black wires - look for 0.05 volts or less to be ok. Check the output voltage from the Mass Air Flow Sensor on the White wire - specification is less than 0.5 volts key on engine off and 1.0 - 1.3 volts at warm idle. The Green/Orange wire at the Mass Air Flow Sensor is not used. The Mass Air Flow Sensor can test good and still be defective.

    2. Make sure the timing belt is not off a tooth. Can check ignition timing to see if one bank is on. May need to get into compression on each bank but a timing belt off a tooth or two will idle poorly but can run better at higher RPM.

    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

    My Subaru?


    I would say that the sensor may be bad the only other thing that i can think of is that the PCM lost its idle settings. then it is trying to relearn the idle setting and adjusting for the air sensor and/or the O2 sensor.
