I have a 2002 Wrangler Sport with no manual. Does anyone have a guide for what the dash warning lights are? I just had one come on but no idea what it means.

What is the warning light you see?

What does it look like or say?

It looks square and I think it is to the left of the check guages light that is not lit up.

Is it this one?



If so then that is your check engine light.


You can go here to see what the codes are:

TJ Error codes



And you can go here to see that they mean or do a search on here:

That is the check engine light.

Yes that is the one.

Well hopefully it won’t be too bad!

Here is the link to Jeeps web site so you can download the 2004 owner’s manual, it wont be exactly what you need but darn close. I don’t have one for mine either but Wrangler Forum is the only owner’s manual I need, you can figure anything out here!

BTW... Welcome to the forum!

I tried the Push Odometer and turn the key I got it to cycle through the lights and all gauges work. I tried the on off three times and got P340

P0340 = No Cam Signal At PCM

There is a TSB (technical service bulletin) out for the cam gears on late model wranglers.

I'll see if I can dig it up for you bud.

Okay Thanks will check back later. Tried opening closing the gas cap based on instructions from 2004 manual. Cycled through the gauges and indicators and now the light is off. I will keep my eye on it. Hope it is not the problem reading the cam. P0340 Thanks for the info and help.

There's a thunder sign on the dashboard. And we are clueless what it means.
