You need oxygen socket and 3/8 ratchet wrench.easy way to replace oxygen sensor is to start vechicle let run few minutes just enough to get exhaust system hot so it will make it easier remove oxygen sensor.just remove heat shields disconnect oxygen sensor electrical connector then replace oxygen sensor.use penetrating oil let it soak around oxygen sensor for 20 minutes that will help make it easier to remove sensor.
Thanks, im having trouble locating where the oxygen sensor is though.
Hey i remember we used to be able to post videos of our problems on here & now i cant see where to do that at?
you have one oxygen sensor in the exhaust manifold look at catalytic converter should have oxygen sensor in the converter

bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know

My 2002 Camry V6 is having some issues. Went in for an oil change that turned into a front struts, springs and mounts job. Then I was having some problem in the higher speeds waiting for the car to shift, so had a tune up done, which meant new spark plugs, and of course, the gasket! So now I am out about 1K and now the check engine light comes on. Had it checked out and and a catalytic code came up. They fiddled with it and got the check engine light off, but now the VSC and TRAC OFF lights are on. What does all this mean? Should I take the plunge and get the cat converter done now?
