Default Front o2 sensor question

I did search for quite a while, so bear with me.

About 16 months ago my 04 sti had the ftont o2 sensor changed out due to slight surging at 0-5% throttle.

Now I am getting the same thing, only stronger surging. I am out of basic warranty, so I am looking for a way to check the front o2. The deaker sez there are 5 o2 sensors on my car, which I have never heard before.

Does the utec show o2 sensor voltage??

Thanks for help!
