Cancelling engine codes

My son owns a olds alero the dealer told him he needed a new mass airflow sensor, they wanted over $400.00, he picked one up from a reputable salvage dealer that tested it as good for $50.00 and it took my son 10 minutes to install including the time to find the right tools. Is there away to cancel the engine code that has the check engine light on?

    What else could cause the check engine code to read mass airflow sensor?


    OBD Codes have nothing to do with telling you the
    problem or the need to replace parts

    Codes are used to diagnose the system with the fault,
    that set the codes

    Have to component test the entire vehicle system, to find a
    problem

    You were only told about the code

    No one can tell you what the problems may be, until the vehicle
    is properly tested to even find a problem

    Code 157


    Error code 157 on your vehicle indicates a problem with your mass airflow sensor. The mass airflow sensor gives a reading based on the air intake and output within the engine compartment. A properly functioning sensor will contribute to better fuel economy. In some instances, you may be able to clean your mass airflow sensor to clear the error code, but the error will most likely return in a short time. Fortunately, replacing the mass airflow sensor is a reasonably simple repair.

    I own a 2003 Nissan Altima SE 3.5L. Recently, my car sounds like it is stuck in 2nd gear. The RPM's do not run high but the car sounds like it is racing in second gear. This is an automatic. Help?!


    If your service engine soon light is on, go to autozone and have the code pulled up. Sounds like you are in limp mode (safe mode). I suspect it is your mass airflow sensor. Its easy to replace but expensive. I recommend getting one from a junk yard and installing it yourself. if you dont have any mechanical experience dont worry. As soon as you see one it will be obvious you dont need experience. It is in the middle of the big tube that connects your air filter to the throttle body. All you need is a screw driver and disconnect one electrical connector. Again, not worth buying new...they cost over $350 new but only $60 at junk yard.

    If you want a quicker way to check, dissconnect the big tube from the intake manifold, in essance letting air run directly to the throttle body without going thru the air filter or mass airflow sensor. If the car runs fine with it dissconnected, its the mass airflow sensor. Buy some mass airflow sensor cleaner at an auto store (its specifically made and named mass airflow sensor cleaner). Try to clean it first...Dont touch anything inside with your finger tho.

    Sorry if Im sounding like a school teacher but Im not sure of your mechanical knowledge or ability.

    If not none of this works , you will have to pull up the code.

    Engine dies out above 2500 RPM, picks back up at 2000 RPM


    That's a characteristic of Nissan engines when the mass airflow sensor is not working. My 1990 300ZX was set up the same way - when the mass air sensor fails, the car won't rev above 2500RPM in order to safeguard the engine. Get some air intake/throttle body cleaner and clean the mass air sensor. Get some electrical contact cleaner and clean the electrical contacts on the harness plug that plugs into the sensor. If that doesn't cure the problem, you'll need a new sensor.

    The mass air sensor is in the 3-4" diameter pipe between the airbox and the throttle body.

    MASS AIR FLOW SENSOR REPLACEMENT & DIAGRAMS


    Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.
