Default Re: O2 sensors - which is which?

Thanks for that.

Well, this time I THINK it's easy, since B1 S1 started acting up in the fall, then was OK. Then it started again just as I went into the hospital.
For the past two weeks, both B1 S1 and B2 S1 are acting up - so I'm thinking of just changing them both.
