Which O2 sensor is Bank1 sensor 1

[deermagnet]

So were did you get this diagram?????

That's from the '99 VX repair manual. The sensor is not always the problem. The sensor is sensing a problem somewhere else. I'm on all my original O2 sensors after 252,000 miles, so they are not prone to failure.

I'll look up info on that code later tonight or maybe someone else can post it sooner.
