On the 98 Mazda 626 there are two oxygen sensors, one is located at the front bottom of engine on the drivers side. If I remember correctly it requires a 23mm wrench to remove. The other sensor is located under the bottom on the exhaust pipe just behind the cat. converter. I hope this will lead you in the right direction and good luck.
