Four digit codes are brand/model specific, meaning those codes can mean different things for different cars.
Generally, 2198 means you have a problem with one of the O2 sensors, or the fuel mixture. You would need to get the test procedure for your make and model to proceed.

SOURCE: 02 sedona hard time starting and mass airflow sensor issues


Appreciate the direct "Ask Me".

Hard starting could be caused by a number of faults such as weak battery corroded/loose battery terminals, fuel delivery issues and others which may include as you posted the MAF sensor. In my country however, most Kias have a peculiarity. They like to be well warmed up (even if it is hot here). Hard starting specially after short hops/trips is actually the ECU/ECM/Control Module or the car's computer getting mixed sensory inputs. The corrective action is to warm up the car fully before using. In some instances, it may also be required to reset the computer by removing the negative battery terminal for a few minutes. Pls bear in mind that some alarms are triggered this way and/or some car stereos would require a security code if the battery is removed.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

SOURCE: mass air meter not reading vane postion

hey rob_andersen,

yes their is a way to replace the mass air flow. Get a can of brake clean or throttle cleaner, throttle cleaner is going to work best. remove the until and spray it down with throttle clean, let it dry for about 15 min. and reinstall it.

Now a little warning for you, IF their is no visual damage to the mass air flow then you can do this successfully. Now the reason why I always replace them instead of spraying them down is because is MOST cases the mass air flow will start acting up again. Sometimes it takes a weeks, sometimes months, sometimes years its hard to say.

But the worst you have to loose, is it doenst work an your out 5 bucks for the can of fluid.

Yes, replace the MAF, then check if the lean condition goes away. It should.

MAF's are sensitive to cleaning. Sometimes it works, other times it doesn't.

I have a Buick lasabre 3800 and on my mass airflow sensor one wire is clean and one lookes burnt . Would that cause my car to act up?

Yes, a dirty or bad mass airflow sensor can cause a car to run badly. I had a 1999 Mazda Protege that had this problem. You can get a can of mass airflow sensor cleaner from an auto parts store. Be careful to hold the can a few inches away from the wires so as not to break anything. Mass Airflow Sensors are fragile. Let it dry before putting it back in the car. If your car has the check engine light on, they can check the code for your as well. You could go to Autozone, Advanced Auto Parts, Oreilly's, etc. CRC Mass Air Flow MAF Sensor Cleaner Instructional Video

    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.

    You very likely have a fuel pressure problem or a problem with the MAF(mass airflow) sensor, check the fuel pressure and if that is ok I would suggest you replace the MAF. It is located in the air intake hose to the engine. A picture of the MAF is below.

    Anytime you make a change to any part of the emissions system, its best to disconnect the
    battery for a few minutes. If you don't, the computer retains the fault code and it will usually keep
    coming back. When all power is lost to the computer, it will do a complete scan when reconnected
    and engine started. Try disconnecting the battery for a few minutes then reconnect and see what happens.
