Have a 2000 Tundra V8 with 92K. O2 sensor ( past the converter ) needs replacing. Is there anything to changing it. Where is located? Anything need to be done after changing it? Priced OEM at AutoZone at $179. Thanks!

 

There are 4 alltogether- 2 on each side. 1 before and 1 after the cats. Crawl under there and you'll see them in the exhaust. You might want to check to make sure they have a good connection as sometime some grit will get in there and corrode the contacts and give a false failure MIL

They can be tuff to get out, but if you soak them with PB Blaster or the like, they will come out. When putting the new ones in be careful not to cross thread the bung or you will be bummin.

Also Sparkplugs.com has a better price on them

Good luck!

 

If the code says the rear, do you replace both?

 

While you're in there messing around, pick up a set of SSA headers from ebay for $100 and slap those bad boys on.

 

No it is either bank 1 or bank 2. Who read the code for you?

 

The code was read at AutoZone. It said that the bank 2 sensor was bad. I just noticed on several sites that they mentioned front right, front left, back right, back left. The guy at AutoZone said to change them both(rear). Thanks
