How to Replace 2007 - 2012 Rav4 O2 Sensor

[@Mr._L30.]

I have 240k miles on my RAV4, would you recommend me replacing the sensor even though I don’t have a check engine light on?

If it ain't broke, don't fix it...

[@Mr._L30.]

Is that bank one sensor two?

@@reyc3709 There is just one bank since its an L4, but the video shows bank 1 sensor 2 replacement. It turned out to be Sensor 1 (A/F) in the exhaust manifold.
