Hey Mike. I can't find any code P1198. How did you check the code? You may need to recheck and verify what the code is.
Do you have a P1128? I've seen this a few times. There is a TSB specifying how to check the air flow sensor for this code on 1.5L Accents. Usually, the air flow sensor is the problem when this code occurs.

It's the sensor that bolts on to the air cleaner housing. To test, you would need to do a performance test, not just check it with a multimeter while it's sitting there. There's information in the bulletin that will allow anyone with an OBD-II scanner (not just a code reader) to do the diagnosis.
Go to www.hmaservice.com and check out the service bulletins for your car. You'll need to register, but it's free.
