The check engine light has been included in passenger vehicles for a long time. It's an on-board diagnostic tool that alerts drivers to possible vehicle malfunctions and problems. If you see the check engine light comes on, here's what to do. Don't panicFirst, the check engine light is not an indication of anxiety. There are a variety of reasons the light might come on, but the majority of them aren't emergencies. Certain of the issues the light diagnoses aren't even urgent - for instance, a leaky gas cap can bring on the light on certain kinds of automobiles. It's important to take care of the problem immediately, but you don't have to panic. Identify signs of impending failureAlso, check for other indications of imminent failure. The check engine light typically suggests a problem that needs to be dealt with quickly but shouldn't result in your car crashing. There are instances where the check engine light might signal an emergency. It is possible to determine these by reviewing a few aspects. On certain vehicles, the check engine light may be yellow or red when it is on. The check engine light is yellow. It signifies that there is no emergency and a red indicates that the vehicle should be stopped immediately. To find out whether the check engine light in your car has this dual function, review the check engine light of the owners manual. It is imperative to stop immediately if a check engine lamp is illuminated by red light. A red light on the dashboard indicates that there's a chance of an immediate failure. The reason for the failure could be caused by low oil pressure or low electrical voltage or a high temperature or something else - depending on the indicator light that comes on. If the check engine light is visible and you observe any unusual indications, don't be alarmed. Smoke rising from under the hood, and loud sounds are two indicators that motorists often notice when their vehicles malfunction. Check the Gas CapWhen you stop off from the shoulder or drive until you're at the destination, one of the first items to examine is your vehicle's gas cap. Caps that leak are responsible for only a tiny portion of engine light triggers however it's the most straightforward to test. Make sure the cap is secure and observe whether the light turns off when you tighten the cap. You can decide to drive or have a towAssuming that tightening the cap on your gas tank didn't cause the check engine light to go off, you'll have to decide whether it's safe to operate your vehicle. If you've been forced to stop because of specific warning signals, then your vehicle might not be safe for driving and should be towed into a repair center. Call a tow truck and take your vehicle to the service center. If your vehicle is displaying a yellow check engine light and no other signs of trouble, it is likely that you require service. However, it should still be legal to drive. Contact a service center to set up an appointment with your car. In the meantime, you can operate your vehicle as you normally would -provided you do not have any other issues. Please read the Check Engine CodeWhen the check engine light comes up, your car's onboard computer records a numeric code that describes the specifics of what caused the light to come on. A mechanic will put in a special tool to read these codes once your vehicle is taken to a repair shop. When the code that caused your vehicle's light is read the mechanic will inform you what the problem is. Then, you can collaborate with the mechanic to decide how to address any issues with your vehicle.
