Understanding Your Check Engine Light
What do you do when a warning light on your dashboard is lit? That’s easy: you come by Import Auto Repair in Milton, Georgia, to ensure your vehicle gets the attention it deserves. Warning lights serve several different purposes. Some are intended to let you know that something — your high beams, your airbags — is engaged. Others may indicate something that needs attention, such as your fuel or oil level. Like your transmission fault indicator, others let you know that it’s time for transmission service. Your check engine light isn’t quite as specific. Think of it as a notification that you should get to your local auto shop for check engine light diagnostics as soon as possible. The check engine light is part of your vehicle’s robust on-board diagnostics system (OBD-II), which monitors the engine, transmission, and exhaust system. If a problem is detected in or concerning one of these systems, the light will then illuminate on your dashboard. Internally, a diagnostic trouble code (DTC) is generated and sent to your computer system, later to be retrieved during check engine light diagnostics service. The DTC is what lets us know where the issue lies.
Causes of the Check Engine Light
A multitude of issues of varying degrees can trigger the check engine light to come on. For example, a loose gas cap is enough reason to cause it to come on. When the cap isn’t tightened, vapors can escape the fuel tank, ultimately reducing fuel efficiency and increasing emissions. We recommend first checking to see if the gas cap is correctly screwed on if you recently filled it up. Spark plugs are a pertinent aspect of combustion, and if they are not firing right, your engine’s performance is hindered, and the release of hydrocarbon emissions is increased. The catalytic converter is responsible for transforming carbon monoxide into carbon dioxide. When this component becomes compromised, fuel economy and performance are reduced, and emissions are increased. A range of sensors and modules is incorporated in vehicles, and an issue with any one of these can trigger the light. If the mass airflow sensor is defective, the correct air/fuel ratio to run the engine can be off, ultimately affecting engine performance. These are just a few examples behind the engine light, and the only way to determine the exact issue is through professional check engine light diagnostics.
Diagnosing Check Engine Light Problems
By itself, in other words, the check engine light could mean nearly anything in relation to the engine, transmission, and exhaust. So, how are you supposed to fix your car? You don’t have to, but we will. We’ll use our advanced OBD-II diagnostic reader tools that retrieve and interpret the diagnostic trouble codes generated by your vehicle. Our check engine light diagnostic equipment is accurate, and our certified technicians are experienced, so you’ll get the right diagnosis and repair right away, using top-grade parts. Be it a faulty oxygen sensor or a vacuum leak, when the check engine light comes on, it’s important to visit our auto shop sooner rather than later. If it is a steady glow and no other warning lights are lit, you have time to get to our shop. If the light is blinking, or if other warnings are showing, however, we suggest finding somewhere safe to pull over and call us for guidance. A flashing check engine light indicates a serious issue and should be addressed promptly.
