When it comes to the fuel injection system in your automobile there is no question that to function properly, all the electronic sensors in your vehicle must be up to snuff and functioning properly. Proper information and data must be fed to your car or truck’s onboard computer system. Sure the electronics in your car in 2010 / 2011 dwarf NASA’s moon shot computer systems yet it is a case of “Garbage In Garbage Out” if the automotive electronic sensors in your vehicle are not functioning 100 % , each and every drive and time you start your automobile .

Very simply put, if one or more of the sensors are faulty, then the computer will not be able to determine the correct fuel mixture. Most electronic fuel systems have a certain amount of built in diagnostics to detect sensor problems. If a sensor is not producing a signal – then the onboard computer or banks of smaller computers will detect a sensor problem or problems.

If an electronic sensor that reports on your fuel system in your vehicle is not producing a data signal, the computer may note it and store a “trouble code” in its internal memory. Depending on the nature of the failure, it may cause a warning light, such as the dreaded “check engine” light on your dash to light up or come on. At that point you should take your car to a trained professional who knows how to diagnose and troubleshoot electronic fuel injection for diagnosis and repair. Correct diagnosis depends on following the step by step instructions in the manufacturers detailed repair manuals. Trying to figure out what is wrong without the correct manuals, or discs of specific data and manuals to refer to is virtually impossible. It’s worse than finding a needle in a haystack. Anyone who tells you otherwise is simply wrong or incredibly lucky – one time only.

When the mechanic gets into your car, he or she will put a sophisticated computerized electronic device into a self diagnostic mode so it will give them a quick and detailed readout of any and all trouble codes which are stored in the memory of the onboard system. In the auto service trades this is simply referred to as “reading the codes”. In some vehicles the codes can alternatively be read, in some cases and situations by actually counting the flashes of the check engine light while on others such specialized diagnostic test equipment is needed to fully read and evaluate the codes. From there on the mechanic or service technician will have to follow a step by step test sequence until the fault is fully and complexly isolated. Regardless in most cases the reference will be have to made back to a specific manual or list of codes as supplied by the manufacturer or maker of the car , or a reputable third party reference source disk , book or online repair and diagnosis service.

Thus if the check engine light comes or lights up or your dash you can bet it’s a fairly sophisticated system that requires a professional to diagnose the problem. Once diagnosed its your choice as to which shop , mechanic or even backyard mechanic should repair the vehicle engine or which components need to be replaced. To simply reset the codes without taking steps to correct the problem is simply false economy and will not leave you with a reliable or trouble free driving experience down the road.
