Primary o2 Sensor
Went bad.
I've heard the aftermarket ones don't work. In all the years this car's been out i'm sure someone has replaced one...
It's a 2000 if there's any differentiation amongst the years.

Get the OEM part (Not sure if its NGK or Bosch), replacing the primary and/or secondary is really really easy. Just use some PB blaster before you attempt it.
I helped Sean_Halla replace his, the hardest part was unscrewing the bolt, it was stuck on there like glue. After that it was really simple.
If you have a jack, stands, and basic Metric tool set, either a wrench or an O2 sensor socket, I can help by pointing out what you need to do

I know you said primary, but I replaced my downstream (the one mounted on the cat) with an NTK/NGK I found on Amazon. Cost me $75, and to my surprise, exactly the same as as the one I that was bad. Reading the boards, I think that if you stay away from universal O2 sensors, you be ok, 06 and up AP2 seem to be more sensitive to what you use. Another thing I learned is that the cat will fail and destroy the O2 sensor, as was my case.

Usually it happens the other way around -- usually the O2 sensor fails, which causes the engine to run too rich, which then kills the catalytic converter.

i bought a aftermarket Delphi brand for my secondary from www.rockauto.com and it works great... No cell and no issues... Going on about 6 months since i replaced it...

My primary sensor is going out on my S2000. Much as I hated to pay up, I ordered OEM due to mixed results I've heard about aftermarket ones. I believe the primary is more important for tuning, so I might be willing to go aftermarket if/when my secondary goes out.
