1998 Hyundai Accent Check Engine Light (MAF Sensor)

My 1998 Hyundai Accent is running poorly. It idles very bad, and the check engine light is on. I tried to have the computer scanned so I could mail you the code number, but it won’t scan. Have you seen this before? I’m hoping I’m not the only one this has happenned to.”

Yes, it’s a pretty common problem in those Hyundais as they age. I fixed one about five months ago with the same exact symptoms. It had a bad mass airflow sensor. This sensor measures how much air goes into the engine, then the computer uses this information to send the correct amount of gas through the fuel injectors. They will often go bad and will not only make the engine idle poorly, they will knock out the computer’s code section and make it impossible to retrieve any trouble codes. So have that mass airflow sensor checked out and replaced if it’s bad. It’s a pretty simple job, you just unbolt the old unit and bolt in the new one. Most people can do it in about five minutes. And any good auto parts store could get you a rebuilt unit to save money.
