I ordered an "OES Genuine Throttle Position Sensor" from amazon recently because it was only $23 and I love taking risks on low priced aftermarket parts. Actually, I'm just cheap. What I received was an OEM KIA 35170-37100FFF TPS.
Now I know the Hyundai part number is the same minus the FFF, so I googled the KIA part number and found some info stating that this TPS is an improved version made for Optima's and Sportage's that have hesitation issues. Here's the service bulletin...

I don't know if the same problem TPS was ever used in the tib or not, but I can say mine has been idling and running a lot smoother since installing this TPS.
The idle throttle position now reads 5.1% vs. 11% with the original. This is in the range it's supposed to be in. I forgot to check what the WOT % is.
Anyway, if you're in the market for a new TPS I suggest you give this one a try.
