Olney area - check engine light

Anyone with those fancy gadgets that can give me what is wrong with my jeep. Check engine light is on. If i take to a shop they are going to charge me to tell me whats wrong. If not, I will either suck it up or buy a device on Amazon. Does anyone have one that I can come to you or meet up. Or suggest one that works well that I can purchase. Thanks.

autozone will read the code to you for free. then you can decide if the issue requires the dealer. also, double check you gas cap that could set if off if it isn't on there right.

What year is your Jeep? I forget what year it started, but usually you can cycle the key from the ACC position to the ON position 3 times and it will display where the odometer usually is. So, ACC, ON, ACC, ON, ACC, ON, then leave it and it should show you what code/codes is/are stored in the computer. It will run through the code(s) that the computer has then it will say "done". I want to say Jeep (and Chrysler products in general) started doing that in 1999 or so. I'd give that a shot, or run by an AutoZone...I'm pretty sure there's one down in Aspen Hill. I'd run the code for you, but I can't find my scanner to save my life (cheap-o AutoZone one, but it did the trick). As far as scanners go, if all you're looking to do is scan codes and clear them, then the cheapest OBDII one you can find will work just fine.

yea Drew is talking about OBD1 vs OBD2, Jeep started putting OBD2 in the TJs (1996) OBD1 in the YJs. If you have a YJ I have the whole thing to make that work along with the code read outs

Thanks everyone.... I have an '03. I will try this key trick. It turns out that i have a small EVAP leak somewhere. Funny story.... as i was driving to AZone on my lunch break the light went OFF. Doesn't that always happen when you take your car in. The vehicle will never make the sound you hear everyday for weeks. Now that that has cleared itself, which could have been the gas cap?
I now have an airbag light that has come on. The best part of the story is that when I honk the horn, the light goes off????? Anyone ever heard of such a thing? I know they are connected somehow, but that is just strange. Note to self - before getting into an accident, Honk your horn at the guy before he hits you!
