Car: 1990 Nissan Maxima

Hi! I have a 1990 Maxima and, according to the code given to me by the ECU, I need to replace my heated oxygen sensor. I saw in a list of codes for that model of car that there are two o2 sensors listed: Heated Oxygen Sensor, and Oxygen Sensor. Are there two o2 sensors on the '90 Maxima or just one? Which one is the Heated Oxygen Sensor, and where is it located? I'd love to fix this myself.

Thanks!
