it's the thing sticking out of the exhaust with a wire attached to it...if it doesn't have one and it's causing problems then you probably have an aftermarket exhaust and you need to weld a bung on the exhaust to attach one

o2 sensors are in the exhaust Usually in front of the catalytic converter near or in the exhaust manifold.

The are two o2 sensors in an 04 Sentra. One is called the front sensor, and it is in the engine compartment, in the exhaust manifold. The other, the rear one, is in the exhaust pipe under the car, past the catalytic converter.

check your exhaust system there should be a wire running in to your exhaust tat is your o2 sensor good luck There are two o2 sensors, one in the engine and one coming out of the Cat Converter in the exhaust system.

Gas mileage also went down and I just replaced o2 sensors.

Downstream O2 sensor is an O2 sensor after the catalytic converter. Upstream O2 sensor is an O2 sensor before the catalytic converter.

It is in the exhaust pipe right after the exhaust manifold.

YES - FOUR One type of sensor is for the ABS ( brake system ).

You got to take out air intake tubes out, then with special nut for oxygen sensors unscrew the o2 sensor with few extensions

User Avatar

The O2 sensor should be located just upstream from the catalytic converter in the exhaust stream. look for a metal tube with 2 wires coming out of it screwed into the top of the pipe.

User Avatar

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

I had a very similar problem with my 1996 Nissan truck. New plugs, wires, distributor and rotor only partly solved the problem. Then I replaced the O2 sensor and the probelm disappeared completely. Had 130K miles on the truck when replaced and the O2 sensor was shot.
