Why is my service engine soon light on?

There is no mysterious reason your "service engine soon" illuminates on the instrument cluster of your car. If you see a "check engine" or a "service engine soon" light in your instrument cluster; your car has stored a diagnostic trouble code. Which means the computer system on your vehicle has detected a problem within various systems it controls. Your car has many different sensors that monitor the various vehicle systems. If the trouble code light has been illuminated your vehicle enters into "limp mode" this means it is running on a predetermined program that causes poor mileage and increased emissions. An engine trouble code reader is an easy to use tool. All 1996 and newer vehicles utilize a "D" style plug-in connector that connects to the code reader. On most vehicles the connector is located at the driver's compartment. Once the code reader is plugged in you can retrieve trouble codes the engine computer has stored in its memory. These codes are the same codes the dealer and repair shops use to diagnose and repair your vehicle, as well as clearing the trouble codes from the computers memory. An engine trouble code reader is an easy to use tool and is a worthwhile investment for future repairs
