Can you remove O2 sensor with wrench?
That’s easy; the nut on the O2 sensor is 22mm so the o2 sensor socket size is 22mm and can easily be removed using a 7/8 wrench.
What should I do if my O2 sensor is stuck?
Allow the O2 sensor and exhaust manifold or exhaust system to cool naturally. Do not throw water on the O2 sensor as this can crack the exhaust manifold or exhaust system when it is cooled too fast. Use an appropriate O2 sensor socket wrench and remove the O2 sensor.
How to get an oxygen sensor out of a manifold?
Brian Eslick from How to Automotive http://www.howtoautomotive.com/ takes you step-by-step through the process of removing an oxygen sensor that is stuck in the manifold. You will need an acetylene torch, a variety of oxygen sensor socket wrenches, penetrating oil, and some leverage.
How can I change the oxygen sensor on my car?
Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it. Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.
How can I find out which oxygen sensor is to blame?
To figure out which sensor is to blame, type the code into an online database like http://www.obdii.com/codes.asp . You can buy a scanner online or at most auto parts stores. If you don’t have one, you could take your vehicle to an auto parts store or mechanic to have them detect the error code.
What’s the best way to remove an O2 sensor?
Spray the penetrating oil on the O2 sensor and allow it to sit for a good 20-30 minutes or overnight would be even better. Afterward, use an O2 sensor socket wrench to break loose the O2 sensor. Sometimes, due to tight spaces, you may have to use a regular metric or standard wrench. Some of the common wrench sizes are 22mm and 27mm or 7/8”.
What to do if a sensor wont Budge?
Spray the base and threads liberally with a heavy-duty penetrating lubricant, such as PB Blaster. Wait for 10 minutes or so and see if the sensor will budge—it usually requires a 7/8″ wrench. If it’s still stubborn, heat up the base and threads with a heat gun (preferable to a torch, since there’s no open flame).

Can a seized oxygen sensor be worn off?
Typically oxygen sensors will come with an anti seized pre applied from factory, however with age this can eventually wear off. You’ll be tackling with both rust and soot in the exhaust, if the sensor has been there for a longer period, there is a greater change of tackling these issues.
