Yes.

The box is up on the right side of the steering column under the dash
and under the cruise control module if you have such.

It can just be unplugged and the light will go out.

On a 91, the module needs to be either unplugged or replaced, it will
not reset.

Though some enterprising soul figured a way to reset the sucker with a
needle and it has been posted here in the past.

I wouldn't bother, who needs a light telling them they must go spend
money to turn the sucker off whether the O2 is still good or not?

In 91 that light was controlled by the engine computer. Earlier Jeeps with the
Renix FI had a separate timer that could be unplugged. The only way to reset
yours is using a scan tool. You have several other options if you just want to
make the light go away.

My book says the 91 still has the timer, but then the Haynes manual has
been known to be off before.

Easy to find out, just look at the side of the steering column, if there
is a little box there, unplug it.
