It's for OBDII (Onboard Bigbrother ???).  The smog police need merely
hook up the connecter and note that there is less oxygen after the
converter.  If you gut the cat, the O2 level will be identical.  Maybe
the next thing they'll come up with is a transponder that will transmit
your speed when pinged - or am I being paranoid?

I suppose the engine controller could use the info to detect misfires,
less than perfect combustion, or whatever.  That's what it's for.  Yah,
that's it.  That's the ticket....  ha ha ha  <ahem>
