Best Answer

You have 2 o2 sensors. One is under the hood, forward side of the engine. It is the 3-wire sensor screwed into your exhaust manifold (covered by heat shield). If you follow your exhaust back from there, under the car, just after the catalytic converter, should be the other one.

How do you change the O2 sensor on a '95 Nissan Altima?

the o2 sensor is located in the exhaust manifold. As you pop the hood and look at the engine, you should see a silver colored heat shield. Unplug the old O2 sensor. Then remove the heat shield. Its easier this way (10 MM bolts). Get a O2 sensor socket and remove the sensor and replace. The rear sensor is located in 1 0f 3 places. Either before in or after the catalytic converter. For this one you just get the O2 sensor socket and remove. (When the engine is cold) Madd Dogg 40/40
