depending on what motor you have oxygen sensors are usualy located either half way down before the Y pipe in the exhoust system, or if it's a car some have one located on each side if it's a V6 engine. Most are located before the pipes from each side of a v6 or v8 meet to form the single exhoust system and some i've seen located in the middle of the exhoust manifold (one on each side). If you're problem is the check engine light ( which is the most reason they tend to come on there's one trick that works for many but not all. If you drive mostly in the city and don't take any long distance trips with the car i suggest that evert tune right before you shut it off when you get back home is to step on the gas peddle almost to the floor and just give it that quick rev up then turn the key off and it will shut off. What that does is clean the tips of your injectors off if you've been just putting around town ( My mother had problems with her car and since i told her to start doing that as a routine her light doesn't come on anymore, it always starts no matter how cold it is now, and i don' t have to drive the 18 miles to rescue her before the chickens get up anymore,. What that does is blows all the carbon off the injectors which allows more fuel with a greater emulsification process to occur which ignites fuel much easier. If an injected vehicle idles for an extended period the injectors get carboned over and next time you try to start the emullsified fuel is less oxygenated due to the injectors being carboned up and that causes way less efficient starting conditions to occur. Hope this helps you and it starts much better for you through the winter by following the steps outlined above. Thnx.
