Map sensor
I believe what the code is attempting to tell you is,
The reading the PCM is receiving from the MAF , which you changed, and the electronic throttle control are not rational, in other words, don't make sense.. One of them is off. That could have a few causes and usually a good idea to confirm all good connections first before replacing any parts. The ETC may be giving a rdg that doesn't agree with the MAF rdg. A dirty throttle blade might contribute to something like this.
Did you get any other codes like fuel trim , or rich or lean codes? What symptoms were you getting?

Some Hyundai engines will have a MAF sensor and a MAP sensor,however, the MAP sensor in this application is used as a Baro sensor and is placed near the intake .and can be combined with the MAF sensor. The 4th wire is the tip off.
