AF Bank 1 Sensor 2 Replacement - 4.2 2003 2.0 VVTi

[Chud]

I've done my best to see if anyone has done a tutorial etc. in here on this but I need to replace B1 S2 on my Rav.

If I've understood everything right then it is located beneath the CAT on the right hand side (when facing the front of the car) but it looks like a right b***** to get to. Without a guide to follow I'm looking at removing the plastic tray under the front of the car and going in from underneath, is that the right thing to do?

If I recall I changed mine from the top with no problem, I unclipped the plug and got a proper sensor socket which has a slot in it and I also done it when the engine and manifold was hot as it unscrews easier, fit a genuine denso one as will fit spot on and you may find you have to reset the fault code a few times until it settles down , defo a job you can do yourself.
