Buy the new sensor and it comes with instructions. The tricky part is finding it. On a forester its located on the up pipe manifold. Since that's a boxer engine, the mainfold is low, you have to get under the car. A bosch O2 sensor has a nice detail set of instructions for replacement.
Location varies with model of Subaru, but most are installed just upstream (towards the engine) from the catalytic converter located under the right hand drive shaft. Mike is correct-- you must get under the car to replace. Make sure you follow safety and use a good set of car ramps on level solid ground to raise the car, or use jack stands. Best to work on a cool engine/car. Unplug the wire leading from the O2 sensor, then unscrew the sensor to remove. The old one may be stuck quite well, but it unscrews like a spark plug. When installing the new one, avoid getting dirt, grease (or anti-sieze) on the sensing tip of the new unit, and just screw back in. It will turn easily for a few turns, then turn harder for about 1/2 turn, then it just stops turning. You have compressed the sealing washer correctly. Remove your wrench, plug the new sensor back in, and lower the car. Do not be surprised if the computer is a bit confused for the first 20 minutes of driving-- it will be re-learning the correct new oxygen sensor.
When a Subaru has a faulty O2 sensor the fuel management is out of whack.
To replace the oxygen sensor on a Honda Odyssey, first unscrew the sensor. Then use a 22 mm socket or 7/8 inch wrench to replace the oxygen sensor.
You cannot bypass this sensor.
The code 32 for a Subaru vehicle is for the coolant sensor or the oxygen circuit.
The 2002 VW oxygen sensor is quite simple to replace. Remove the wiring harness. The oxygen sensor will simply pull out.
To replace the oxygen sensor disconnect the oxygen sensor electrical connector. Use an oxygen sensor socket to remove the sensor. spray the sensor with penetration oil if it is difficult to loosen. install in reverse.
An Oxygen sensor does not reset. You have to replace them and yes they are expensive.
You bring it to a service station and tell them to replace the oxygen sensor.
how do you replace oxygen sensor of 2001 bmw 318 ci es
Absolutely. Not just on Subaru but every car built that has an oxygen sensor. And they all do.
Unplug sensor--- sometimes you can get a wrench on the sensor if not you will have to purchase the special socket.Genuine parts are often high so you can get the sensor at an auto store directions are included with the sensor as how to attach the pigtail and ude the heat shrink tubing suppied
Probably referring to a heated oxygen sensor.
You can not successfully clean an oxygen sensor. You need to replace it.

Take it to the dealership.... Its real simple take the car jack it up take off the housing cover where the oxygen sensor is at then un plug the sensor, and replace...
Oxygen sensor on 1990 Subaru Legacy is under car, just behind engine where exhaust manifolds join but before catalytic converter. Wires run up right side of bellhousing and connect into wiring harness.
labor cost to change an oxygen sensor in a 1995 toyota avalon
If someone could please explain who to get to the oxygen sensor and explain where it is for sure?
Just unplug the electrical connector and then unscrew the oxygen sensor out of the exhaust pipe.
The oxygen sensor measures the amount of oxygen in the exhaust gases. Theoretically, if the fuel mix is perfect, then there should be no oxygen in the burned gas ... if it detects O2 it assumes that there wasn't enough fuel ... and adds more.

You can replace the oxygen sensor on a 2002 lincoln LS by first unplugging the old one and then making sure the tread marks are lined up replace it with the new one.
Both o2 sensors are located on catalytic converter. Sensor closest to front of car is upstream sensor. Sensor closest to rr of car is downstream sensor.
