O2 sensor question

[TheMagi]

I've been told there are supposed to be two O2 sensors on my car, but there is only one on mine. It's an 87 Lx-i. Am I missing something?

[shepherd79]

nope you are correct.
you have only one stock sensor.
two sensors were on 88-89 EFi accords.

88-89 efi are a different model motor than 87 and 86 (or is 86 only carb?) ? That's something good to know...

i have an EFI '86

[Robs89LXi]

Why are there two O2 sensors on the '89?

one is narrowband, one is wideband, supposed to reduce emissions etc
