I have a 2003 Grand Cherokee Laredo and after about a year, the check engine light came on. Took it to the dealership and turned out it was a loose gas cap. No problem, my fault. Then it happened again about six months later. Same thing again, but this time I'm sure the gas cap was tight. Dealer said the cap might be bad. So a month later it came on again. Changed gas cap at advice of dealer. Now the light will come on within a day of resetting it. I'm convinced its not the gas cap...and it runs perfectly fine. Ive just left the light on for about a year now. Is there some other sensor in the system that anybody knows about that will keep this light on? Any ideas would be appreciated. Ive heard this is a common problem.

I tried checking for a code by holding the odo reset and turning on the ket, but none showed up. Going to try the code reader at Autozone tomorrow.

See what Autozone says - there are a bunch of different things that will cause the light to come on. Find out what the code is and narrow it down from there.
