It would be nice if something was sounding or acting funny. Keep an eye out for something like that because other wise youll have no idea unless you get one of those scanners to read the codes and find out what it is.
Live for those who have died for your freedom.
This happened to me recently during an off-road trip. In my case the connector to the rear exhaust sensor had somehow come unplugged and was hanging down below the car, hence the CEL. This might be worth checking as branches or similar might have snagged the wiring underneath?
It took a few engine start/stop cycles before the light cleared.

If you have a check engine light, unless you stumble onto the problem, the best bet is to get the code read so you have some hard data to go on. Use the OBD2 technology on your 99.
Some of the big box parts store (Advance Auto Zone) will plug and read your codes for free in the hopes that you will buy necessary parts from them. Otherwise, any shop can do it and shouldn't charge you much for just reading them.

The CEL comes on because a sensor throws an odd reading or non at all. I have to laugh when ppl check all there fluids but cant figure out why the light is on.
But you prob wont be abke to figure it out unless you pull the code.
Why not just go to autozone or advanced auto and get your codes read for free

Go to the local AutoZone. They will attach an OBD-II scanner to the output port on the bus, and read any codes stored in the ECU that will have triggered the CEL.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
