2012 JK Unlimited - check engine light
 

Hi Guys,
Got about 4000 km on my Jeep and last night the check engine light came on.
It actually was the first time I got the car startor to work, and when I got in I noticed the light on. :eek:
Also my ECO light doesn't come on anymore either.
Called the dealership but service is closed until January 4th.

Anyone else experience this?

Gone!!
Tightened the gas cap, I think that's what made the light go away.
Didn't show any code, just ------------.

Will check the fuel mileage and see if that changed.

Anytime I see a code I always check the gas cap first, especially if I was recently at a full service gas station. If that doesn't work I disconnect the battery for 5 minutes. If the check engine light comes back on within a few minutes of driving then I know I have to make a trip to the dealer.
