The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

YOUR ENGINE CONTROL MODULE CAN HAVE SOME OF THE PARAMETERS RE-PROGRAMED/ADJUSTED.

But if you want to radically reprogram your engine control module you will have to go to performance center, if your car has an automatic transmission engine control module and transmission control module talk to each other and depending upon the intelligence of the components they might watch each others peraminators,if they are out of these it could cause the check engine or check transmission light to be turned on,
