justin97, How much of a pain is it to change bank 1 sensor 1? I changed bank 1 sensor 2 with a bosch, a couple days later the check engine light came back on. Both of these sensors are reading bad, hopefully the one caused the other to read bad again. Thanks

I have a '98 ES 300, check engine light came on, took it to a Toyota dealer down the street to read the code, bad oxygen sensor. They stated it was bank 1 sensor 2, can someone please tell me it's location and if it's difficult to get at? Thank You in advance.
