If you have ever had the “check engine” light come on in your car, chances are you probably thought, “What is wrong with my car?” If you have ever asked that question, you have one thing correct, there is something wrong with your vehicle. A recent study shows about 10 percent of cars on the road currently have their check engine light on. The light has a variety of meanings and there could be a number of issues wrong with the vehicle.
A check engine light is one of the many lights on your vehicle’s onboard diagnostics. When the car’s computer system detects a problem, the light comes on, and the computer stores a code. This code can be read with a diagnostic computer at a repair shop to tell them what’s wrong.
What does the check engine light mean?
There are several reasons why a check engine light comes on in a car. In general, the light is an indication there is a problem with your vehicle’s emissions system. More specifically, it could mean there is a loose gas cap or the engine is misfiring. Other reasons include needing to replace the O2 sensor, catalytic converter, mass airflow sensor, or spark plugs.
What to do
If your check engine light illuminates, the vehicle should be checked by an automotive repair technician to determine the problem. If the light is blinking, there could be a serious problem with the vehicle, such as a misfiring engine, and the car should be stopped as soon as possible.
A steady light could be one of the less urgent issues, but the car should still be taken to an automotive repair shop for a diagnostics check. There may be a problem that could further damage your engine or consume excess fuel if not addressed. Either can cause more costs in the long run.
