At some point in time if you drive a car ranging from 1996 to 2010 model, you have seen that yellowish, bright light pop up on your car's gauge cluster. For some vehicles it might be the words "check engine," for others simply a picture of a wrench. Many drivers have no idea what this simple little light means.
This light is an indicator for all cars that something is not functioning right within the mechanics of the vehicle. It can be anything from a loose gas cap to a pulsating misfire.
The "check engine" light is part of your car's so-called onboard diagnostics (OBD) system. This computer system ultimately scans the car constantly to monitor all of the internal functions to keep it operating and regulates functions such as RPMs, fuel mixture and ignition timing.
When the OBD system detects a function it can't correct on its own, it illuminates the check engine light on the dash. When this happens, a trouble code is sent and stored into a computer. A specific computer scanner is needed to read the code. The scanner can be rented at any auto-parts store, and employees are often willing to help you.
According to the Consumer Reports website, manufacturers originally used the OBD system to help technicians pinpoint and troubleshoot malfunctions. But now, the systems are required under federal laws governing automotive emissions.
Beginning in 1996, manufactures were required under federal law to install a much more sophisticated computer system known as OBD II. This system monitored heavily on emission functions and was an attempt by car manufactures to improve emissions nationwide.
Now what do you do if you have that annoying, glowing light suddenly appear while you're driving? Don't panic, but this should be taken seriously. This light can be a simple fix, but it also can mean to fix something that could be vital to your vehicles operation like low oil or low coolant levels.
Auto manufactures encourage you to read the owner's manual if applicable to fully understand what exactly the engine light means and what could possibly be hindering your car's performance. However, often times you can check the codes yourself by renting a scan tool like I mentioned earlier. However to fix the problem first hand, most often a mechanic will be needed.
Sometimes people ignore this light and never have a problem, but something is still registering as a malfunction within the system. However, other times the light can be very important and, if ignored, can cause significant damage. Think of the "check engine" light as a thinly-knit safety net — the net itself won't hold your weight forever. Keep your vehicle running properly and when it throws that bright yellowish light in your face, pay attention and take an initiative to fix it.
