Default P0103 code issue

2003 Tiburon V6 2.7. Cold air intake. A few months ago my computer started throwing up several CEL codes. I believed it was my MAF, so I ordered an new aftermarket MAF. Installed and cleared all codes, after about 10 minutes of driving a get a code..P0103. I put my old MAF in and do not get this code. P0103 is the only code I get with the new MAF. I returned the MAF and got another one. This one gives the same, P0103 code. I am starting to think that the problem may be the aftermarket MAF. Should I spend the money for an OEM or go to the junk yard, or is there an issue I am overlooking? Please help.

I wouldn't trust the aftermarket part. Did you try cleaning your original MAF first?

Default p0103

yes I cleaned it with a good quality electrical cleaner. Did not help. I am thinking I should just go to a junk yard and try an OEM one.

I got the same issue with my 2000 accent and can't clear the code P0103. I've tried just about everything I can think of to see if it's in the MAF sensor or the wiring. I got a multimeter and not sure what the voltages are supposed to be and where to connect the power to the sensor to see if it reads 12v, the sensor ground, and the MAF signal. There's an IAT somewhere towards the right side of the connections. What are the voltages supposed to be and how do I check them?
