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.
Buy a Haynes or Chiltons Manual. They have wiring diagrams in the back with wire colors listed.
you might try www.haynes.com, these are the folks that have all the manuals for wiring etc.
There's no universal color code for oxygen sensor wiring. Buy the right sensor, period. If you're buying a generic sensor for your car (possible, but there are still many different kinds) and need to splice the wires from the new sensor to the car, usually the black wire is the ground and the other wire is "hot." With three-wire sensors, try to find a wiring diagram online to match up the colors. It's risky using a voltmeter or test light to find the hot wire(s), because you could fry your computer.

Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
i dont think anyone knows i need to know the same qustion
Oxygen sensor #1 screws in to the exhaust manifold just before the headpipe. The hardest part about replacing an oxygen sensor is screwing it out. Sometimes they are a little siezed in from the heat. after you get the old one out, you'll need to make sure you know how to electrically connect the new one. Some of the replacement oxygen sensors have a plug and others need to be spliced in. Just make sure you connect the wires correctly, following the color codes or the directions that came with the replacment sensor. It's relatively easy and a good first auto repair project.
You need a wiring diagram for that vehicle, google it.
Jupiter is orange and Saturn is yellow.
Saturn has a "MACHEESEMOE" type color
