How to Diagnose a Problem With Your Engine
Most people hastily take their car to a professional mechanic when they think that there is a problem with the engine in their car. If the engine light is on there is a way to diagnose the problem without taking your car to a professional automotive mechanic.
How to Diagnose a Problem With Your Engine
Most automotive parts stores, such as O'Reilly Auto Parts and AutoZone, will have equipment that you can use to diagnose an engine problem. They will loan you an Onboard Diagnostic 2 reader in exchange for a major credit card and your driver's license. The clerk will explain how to use the equipment.
Connect the Onboard Diagnostic 2 reader to the connector in your car. The connector is located under the dashboard near the steering wheel on most cars.
Once the equipment is connected, turn the ignition to the "on" position. It is not necessary to start the car.
Write down the codes that appear on the screen of the diagnostic device.
You can purchase a book at the automotive store that explains the codes in detail. The book will provide you step by step instructions on how to take care of the problem.
