Hi.
Have decided to replace my Oxygen sensor, but am having a problem getting the old sensor out. (I already have the new sensor).
Is very tight space. I am thinking that may be best way to break old sensor, then can put socket wrench on and remove the remaining part. Is this a good thing to do?
I am somewhat reluctant, because I hate to ruin a part before I am 100% sure new part fits, etc.

Bad idea. Buy an oxygen sensor socket for $10. You'll need it to properly torque the new sensor to 33 lb-ft. Apply Kroil to old sensor, warm car up, use oxygen sensor socket and breaker bar to remove old sensor, thoroughly clean old threads with brake cleaner, install new sensor, and torque to 33 lb-ft.

Thx.
Where can I find this socket, will places like AutoZone have it?

What is Kroil?

Similar to PB Blaster but better. Kroil smells good, PB Blaster stinks. Kroil is the best industrial penetrant made.

If this is the original sensor, the threads in the exhaust pipe will strip when you remove the old sensor. Don't be afraid to break the old one as it is garbage anyway. You will probably need to bring your car to a good muffler shop to weld a new sensor "plug" into your old pipe to be able to screw in the new sensor

Wow, 7 months later and I get a response to this?? Lol
I have already removed and replaced the sensor. No problem with the threads.
But... in case anyone knows, I do have a problem with this new sensor in that it almost always causes 'check engine' light to come on about 5-15 minutes after car is first cold started. Once I have turned the engine off and re-started, then no more light.. until start cold engine again.
Does this mean that the sensor was bad, or a wrong one (new one has only couple of holes at the end, old one had several)?
Thx.

Bob6831, once your car warms up and is out of the "open loop" program, it throws a code. This is the point where the ECM "passes judgment" on the oxygen sensor. ECMs often don't like universal sensors--best to go OEM.

So... would this light coming on cause my car to fail inspection?

I believe it would.

I don't know if you want to try a BOSCH sensor, but I also have a 95 Pathfinder, and I went through an oxygen sensor almost every 2 years "Nissan Original" until I put in a Bosch replacement. It's been at least 5 years on this one. However, Honda sensors might be better. My 98 Accord has not eaten one yet.

I haven't seen long lasting results with anything Bosch makes for Hondas.
Honda uses NGK and Denso.
Stay away from the generics - they don'y last long either.

Nice... I was able to steel two sensor from a junkyard with a 22mm & 7/8 wrench and some DW-40 or paint thinner will do and let it soak
Going to try see if I can save myself some cash hehehe
