'97 is OBD-2 so it has to have a secondary O2 sensor after the cat. If the one he's looking at is before the cat, it's the primary.

on a '96-'97 Accord there are 2x O2 sensors. One in the header and one in the cat.

what the previous to guys said...OBD2 has two o2 sensors, the one right on the exhuast manifold is the primary sensor and the second one is right after the cat.
