Hello all, I have a question. I just received these 2 codes and nothing ran different. So I drove for a couple of days and the engine light turned off. When I ran another diagnostic the po159 code had been cleared on its own. I have had the issue in the past with my 06 Santa fe and it actually(fixed)itself. I just went ahead and cleared the code. My question is, just because one part of a sensor has a temporary glitch, does that mean that the sensor would need to be replaced or could it just be a computer glitch that resests itself?

It wouldn't clear the code by itself. The code will remain in memory until cleared.

If the light goes away, then it means it hasn't detected the error in a specified amount of time, and turns the light off.

Chances are it will come back. Either the O2 sensor has a problem, the wiring is bad, or you have an exhaust leak.

I figured as much. I took it in and they had to replace an o2 sensor. Not bad for 51k on the clock. Thats the first time It's seen the dealer since new.
