Why would I need to change it and how difficult would it be to change?
theyre easy to change out.
She lets me ride her whenever i want. I buy her shiny things all the time. Give her a kiss and hug every morning and night. Think about her all day and dream about her at night. We have the perfect relationship. Me and my jeep that is.
The way I see it, a Jeep is like sex-when it's good it's terrific, and when it's bad it's still pretty good!
you'd need to change it if it went bad. Could cause your jeep to run too lean or too rich.
I've been driving my jeep with no 02 sensor for a couple weeks and haven't noticed a difference in the way it runs from before the wires got ripped out of the sensor.

Sometimes I question my sanity. Occasionally it replies.
I tried to replace mine over the weekend. After several shots of PB Blaster, each time letting it sit for 20 minutes to an hour, no luck. I let it sit for two days and tried again, still no luck.
I did run the engine for a couple of minutes - I was also changing the fuel filter so needed to ensure the new fuel lines around the filter were secure - but still no luck.
The engine didn't get above 100F, so I may have not let it run long enough to get it hot enough.
Don't have a breaker bar, but did end up buying a sensor socket wrench because my open-ended wrench started to strip it a little.
So what do you suggest... PB blast it first, then drive it around for a while, or the other way around? Never used PB on anything that was subject to heat so I don't know how well it handles 'soaking' and being 200 degrees.
Go to harbor freight and get a breaker bar. You arent going to get it loose without one. Especially if its been in there for a while. You can pick one up for under $20. Archemedies was right, leverage is your friend. Spray it with pb blast while cold, never hot. Let it soak overnight. Take it out and run it hard for 20 minutes to heat the exhaust then use the BB and a good socket to break it free. I have the O2 sensor socket but found it made more sense to cut back the wires on the top when I was removing it and use a 1/2" drive deep well socket.
You can try but there is more torque with a 3 foot pipe on a breaker bar then you can get from an impact. I would try everything I had at my disposal first before buying a new tool.....but I do like shiny new tools too!
