If you want the check engine light goes off one of the cables from the battery but not the best solution is to make a diagnosis with a scanner and you'll realize that you have registered code because if you turn out the light by disconnecting the battery and does not resolve the problem the light will turn on again ...... Thanks
The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
