By and large, the Engine Control Module works by controlling the intersection of the components that make up the engine's energy, in essence air, spark and fuel. From this perspective, it sounds quite simple even as it may be when you break down an engine's basic components. But this said and done, you need to know that the engine control module achieves this key task by it constantly tracking such a vast network of sensors fitted around the car to ensure that the car is in its best operating condition. As such if at all something goes wrong with the systems, the ECM will automatically adjust its settings or where this cannot be, then you will notice that your car will not be able to run normally or run at all. In case there is a problem, the ECM will store a trouble code so to allow the experts or mechanics tell of the problem. There are special scanners purposely designed for this need and over and above this there will be triggered a check engine light on the driver's interface or monitor to alert of an impending or probable issue to be checked on.
The newer engine computer systems as well feature such lightweight and less expensive memory systems. And these can actually be accessed easily from some of the car dealerships around your area. Just as it is with your ordinary PC, your dealership will be able to fix these particular programming issues and do you the necessary systems update on your ECM or alternatively known as ECU.

Thanks to the switch from the mechanical throttle control to the electronic throttle control by many car manufacturers, there has been added yet one more task to the cars' engine computers and systems. Today as a result of this, there is an electronic sensor placed at or close to the gas pedal. This will send signals to the electronic management systems, EMS, which works by evaluating your throttle contact and as such sends a signal to the engine to adjust its fuel dosage into the systems.
By and large, one of the roles of the ECM as a start up procedure is in calibrating the throttle position at idling state. In this, it gets to remind itself and the throttle how it is to run when it is not receiving any gas supply. Actually this happens to be quite an effective remedy to avoiding cases of uneven idle.
