The V6 Saturn typically came equipped with 3 oxygen sensors; one on each exhaust manifold and one after the catalytic converter. The one after the catalytic converter does not typically fail.

It is in the exhaust after the converter.

in the exhaust manifold or before the catalic converter
The downstream O2 sensor was broken and is missing the wiring harness, I have a universal O2 sensor, but need the color codes to wire it properly. It has a purple, pink, black and white.
There are two O2 sensors. One on the exhaust manifold right in front when you open the hood. The other is under the car after the Cat
there are two O2 sensors on this vehicle. one is located just under the hood. if you follow the exhaust down from the front of the engine, the sensor is screwed right into the manifold. the second sensor is under the vehicle just after the catalytic converter.
O2 sensor is located in the exhaust manifold just off the front of your motor. If you open the hood and locate your exhaust manifold, follow it down toward the radiator. you should see a 1-wire sensor sticking out of the exhaust manifold. this is your O2 sensor. you will need either a special Oxygen sensor removal tool, or a 7/8 wrench to remove it.
Depends on what the problem is or what code was set.
there's 4 ho2 sensors total 2 of them are on the front of the engine and the other 2 are on the back of the engine
