Look on the exhaust manifold.

The number of sensors (yes, many cars have 2, 3, or 4) and their location varies with model year, car model, and engine. If you want an exact answer, browse these pages by make and model or post a new question with the specifics.

you will find the oxygen sensor(s) on the exhaust system. there may be more than one. usually before the catalytic converter and one after.

all models except 5.9l v8 models with 2wd are equipped with two o2 sensors.One o2 sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter and one o2 sensor located after the catalytic converter.The 5.9l v8 2wd has 4 sensors.Two upstream sensors( one for each cylinder bank),one is a precatalytic sensor and the fourth sensor is after the catalytic converter.
