i don't know when my o2 sensor was last replaced. shoulvi replace it with an ngk one when i do my plugs. also can you post a link on how to do the o2 sensor.
please and thank you

 

Run your codes and if fine, I'd leave the O2 sensor as is. To replace you just find it screwed into your exhaust and carefully unscrew it and unplug from the wiring harness. I broke one trying to remove mine and stripped the threads in my exhaust and had someone wled a new nut in for me.

 

I agree, only replace the O2 sensor when they start to malfunction and throw a code. To remove, I would suggest spraying the O2 sensor threads with some PB Blaster, let it work in there for a few minutes. An O2 socket tool, which you can use free with the "Autozone Loan Tool program", makes the removal of the sensor easier.

 

I dont know about NGK o2 sensors, I know BOSCH are the OEMs one. If you dont throw a code, you should have no problem. I had a rear heated o2 sensor code once, but it went away and never came back when I resetted the ECU. So, I'm just going to take a look at my o2 sensors and spray/clean them with some brake cleaner, its suppose to do a good job on the sensors. Only a couple of bucks instead of spending $50+ on a new sensor.

 

thank you all for the info.

 

I need to replace my front right O2 sensor. Should I use an anti-sieze compound on the threads of the new one? Or will the heat from the exhaust do some damage?

My OEM sensor came with anti-sieze on the threads. If your sensor doesn't have any, I would put some on. Just be carefull not to get any on the tip of the sensor.
