There are at least two, and up to 4 depending on the year. Follow the exhaust pipe from the manifold to the catalytic converters. There will be two before that point. There may be one or two more after the catalytic converters. They simply unplug, and screw out, reverse that procedure to replace them.

Ther should be 3 or 4 sensors on there. 2 before the catalist and 2 or 1 after them. (Depends on how the exhaust pipes are on it. they had different options)
