There are 4 O2 sensors. They screw into the exhaust pipes and you can use a special O2 wrench or a 21 mm open end wrench.

When you first log on and come to the 5th generation form, the firs threads listed are "stickies". The 7th one down is General Information, Maintenance, and Common Issues.

Click on the link and scroll down about 3 screens and there is a drawing of the exhaust system that has the O2 sensor locations and most of the trouble codes that the O2 sensors could cause. I have included the link below.
