i dont have an owners manual and i wondered if anyone knew the most likely reason? it came on for about 1 hour and then it shut off.
Condition condition and condition. Just like a car.
Have you done maintenance recently or changed oil or had something checked on it? This can happen if the car computer calibration has been reset by the auto shop and now the car is calibrating it's systems again. If not, you may need to take into service to check if you mixture is correct. The light may also come on if it detects something is off in the fuel to air mixture ratio. Anyhow, if the light went off this means there isn't something major going on and it may just be a small thing that is out of place. Your best bet is to drive it around for another couple days or so and see if it comes on again. If it never comes on again then don't worry about it. If it does, take it in for service to have the car diagnosed. It is true, it may also be due to the gas cap not being properly fastened. Good luck!
2011 Chevy Malibu Check Engine Light
The engine check light comes on when a sensor fails or one that is set to monitor the various parts of the engine activates. If it does not stay on, forget it. If you took it in, the Chevrolet repair would not find anything, and you would have to pay for a check up. If it stays on, go in and have it checked out. Then, the Chevrolet repair will have a chance to catch it by the electronic sensor detector. It will give out a code that the mechanics will translate to the problem. Normally it is minor, but it could be major. Keep an eye on it.
