If you are seeing that alarming symbol illuminate your dash that says “Check Engine” or Service Engine Soon,” it’s probably time to get some work done on your car. But, is there any way to know exactly what the problem is if you don’t have a diagnostics test performed on it? The vehicle may even still be running fine, leaving you that much more perplexed.
A number of issues can prompt the light to come on, including a misfiring cylinder caused by a subpar spark plug, a failing O₂ sensor, or an imbalanced air/fuel ratio. If you’re interested in saving some money and attempting to figure out what the problem is on your own, bring your vehicle to a car parts and accessories store such as Autozone. There, you can normally get access to and OBD1 or OBD2 diagnostic computer that scan your car’s system for trouble codes. This service is provided to customers free of charge, saving them a minimum of about $35 if they had chosen to bring it to a mechanic or dealership.
When feedback regarding your vehicle’s errors is gathered from the onboard computer, you will get an idea where the problem lies. Using a comprehensive search engine such as Google, you can then find out exactly what these codes mean. Most of the time, it will narrow it down to the specific part that is malfunctioning (e.g., which O₂ sensor or cylinder is faulty). Once you have your answer, you will be able to buy replacement parts, saving time and money in the process.
In the late 20th century, it became commonplace for cars to contain onboard diagnostics, or OBD codes. These codes, also referred to as “trouble codes,” help assess glitches in your vehicle that you can hopefully repair before you end up stranded somewhere. Obviously, taking heed of these code definitions could save you a great deal of money in the long run. Depending on the brand and year of the automobile, it could contain one of two diagnostic systems. OBD1 systems were installed in vehicles through 1995, and OBD2 systems have been placed in vehicles since 1995. Your vehicle owner’s manual will inform you about which system your car possesses.
