True. The box has to be replaced; no resettting.

Didn't know they weren't available anymore.

My light is on too in my recently bought '92 Laredo.

I have a feeling that bulb is going to get broken next time I remove the dash bezel.

As it states in the link in okcjeepers earlier post, it can only be reset using scan tool.

i know that.

that's what I'm saying. just remove the timer box and toss it, and you won't have any more problems.

remove it, toss it, and then turn your truck on and off 5 times. this should turn off the emiss. light. if it doesn't, disconnect your battery for a few minutes and it should be off.

how many miles on your xj? they're supposed to come on somewhere around 80,000 miles.
Can't seem to find any clear box under there. Any chance of getting a pic of it?

nope.

I don't have a pic of it....never bothered. always removed and tossed them...

you may need to lay down and look up with a flashlight to see it. it may be screwed in up higher to the bottom of the metal dash support. I can't recall exactly. it's near the engine computer tho.

I took that box out on mine, fine since. Also, you can't scan codes we have renix systems.

It is not connected to anything excapt that bulb and it will not harm your vehicle to not have it come on every 60-80 thousand miles. I set all my emmisions up on a chack schedule and I take O2 readings twice a year. If the sensor is within tolerances then I do nothing. If it reads outside the tolerances then I replace it. You.ike me. have only one O2 sensor on the downpipe.

Under the instrument panel and to the right of the steering column is a little black box called an Emissions Maintenance Timer. If your Jeep has cruise control it will be hiding behind the cruise control module. There are no screws to turn or buttons to push, you just throw it away and install a new one! Just that easy.
