O2 sensor(s) How many on a '92

[Dragline]

Just like the title says. Are there one or two on a'92 ???

One, I believe. The "downstream" HEGO sensor didn't seem to make an appearance until OBD-II.

Easy check to make sure - just check the aft end of your catalytic converter and the first foot or so of pipe and see if one is there.

There's only one on my '92.
It's located on the head pipe, just before the catalytic converter.
