95 Nissan Altima check engine light error code 33

Hi all,

I'm getting a return of 33 from my check engine light. From what I've found this points to the O2 sensor but when I call the parts store they tell me there are 2, one at the engine and one at the cat.

does anyone know which one this is pointing to?

Thanks,

Bill

If there are two of them, a code 33 doesn't specify. In my manual, all I see for a code 33 is that "the exhaust gas sensor circuit is open"
