If the vehicle was built with an oxygen sensor, you will need an oxygen sensor.
NO!!!
the oxygen sensor or 02 sensor is usually located on you headers it should take a 5/8 wrench it will have two wires coming off of it.
the oxygen sensor is located between the fist and second muffler. you will need to disconnect the sensor and it will then unscrew out of the exhaust pipe. I just did this on my H6 and I also needed to replace the air mix sensors on each side of the motor. they look just like oxy sensors and my need to be replaced as well. they are located on either side of the headers. the best way to get at them is from under the hood. you will also have to disconnect these sensors from the top and then unscrew them from the headers on each side.
under the heat shield. remove the heat shield and it will be sticking out right above the exhaust headers.
there one on right-its on the side after the cat there's one on the headers right lower side
You need to take a wrench to loosen the oxygen sensor, then you will need to disconnect the cord. Once you have done that you will then pull out the old oxygen sensor.
look at where the headers come off the engine. follow this and there should be a rod like projection sticking out with wires running down from it. that is your O2 sensor.
You can not successfully clean an oxygen sensor. You need to replace it.
You need to get a die that fits. Probably cheaper to buy the sensor
They are located on the downpipes from the headers.
There are two oxygen sensor for Mitsubishi Outlander. Front Oxygen Sensor and Rear Oxygen Sensor
The oxygen sensor on a Buick Rendezvous is located immediately before the converter on the driver's side. You will need either a special socket or a wrench to remove the sensor.
