i have a 99 ga16 and was wondering if the front and rear O2 sensor are the same(part #)
saw part on autozone.com(48.99) front and rear had same part #
saw part at cskauto.com and front and rear had different part # and price
any help appreciated
I can only tell you to look at the O2 sensor off the header and then look at the other behind the Cat. Compare them. The Haynes manual says they're both heated O2 sensors. When I checked mine out, the one off the header was a single wire and the one behind the cat was a three wire. You should be able to see both sensors without removing anything.

Out of curiosity, I checked mine also. My 97's (1.6), front and rear
O2s are both 3 wire units.
