Buch, you're in luck. Bank 2 is the front bank, which is much easier to get at than bank 1.
Now you just need to figure out if it's the top or bottom sensor that needs replacement. The OBDII scanner would tell you this.
So I bought the replacement sensor, but I can't find out where the heck to put it!?
Here's a hint: it goes on the front exhaust manifold, near the oil filter. There are 2 sensors there, one on either side of the cat.
