Don’t just turn it off; fix the problem
The check engine light, also known as the malfunction indicator lamp, illuminates whenever one of your car’s computers or sensors is giving an incorrect reading. Little things, like a loose gas cap or a faulty oxygen sensor, can set off the check engine light, but it can also be an indication of a far more serious problem, such as worn-out timing equipment or a bad catalytic converter. Whatever the cause may be, it’s crucial to visit an auto parts store, repair facility, or dealer to diagnose the issue and make any necessary repairs.
Check engine lights most commonly come in an orange or amber color, with either an icon in the shape of an engine block or words like “check engine.” A steady check engine light is usually an indication of a serious but not urgent problem. If the check engine light starts flashing, however, it means something is wrong under the hood and it needs to be repaired immediately. For example, a misfire can overheat the emissions system and cause a fire, and a timing issue can potentially cause catastrophic damage. In this article, we’ll cover the top reasons why a check engine light comes on and determine a course of action for this scenario.
