Code P0133 popped randomly this morning and I know it might be the sensor. This may sound like a dumb question but: where is the sensor? Which one is it precisely? And are all oxygen sensors the same on auto parts sites or I should be buying a specific one
That code is for the A/F sensor (upstream).
It is located right after the elbow as the exhaust system starts.
You didn't state what year you have so here is a link to a 2008 system.

I've had good luck and recommend NTK or Denso sensors from Rockauto.com or other suppliers.
