Hello everyone, I have been searching how to get the wires disconnected to replace sensor one on bank two on my 2014 IS 250, it seems it goes behind the engine.
It looks like no one has done a write up or a video on this one, all I find are for down stream sensors.
Just to confirm, if you are talking about the sensor in the manifold above the first catalytic converter, that is an Air Fuel Ratio sensor.
It pretty much looks like an O2 sensor, but if you install an O2 sensor in that location it won't work.
Bank 2 is also the drivers side.
Really to get it out just remove the black engine cover and hopefully you have an O2 sensor socket or a claw like tool similar to the Toyota SST below.
If you follow the faint blue wire harness to the connector in the pic, the connector has a release tab to disconnect it from the car harness.

Yes, this is bank 2 sensor 1 air/fuel sensor.
I will look for that, I've already bought the sensor ( not cheap)
Thank you much, you always come thru.
